Opis:
Active suspension systems ease the conflict between comfort and handling. This requires the use of suitable actuators that in turn need to be efficiently controlled. This paper proposes a model-based control approach for a nonlinear suspension actuator. Firstly the concept is derived in the linear framework in order to simplify the synthesis and analysis phase. There a linear model of the actuator is proposed and discussed. Further, this design phase includes a comparison between model-free PID controllers and a newly proposed two-degree-of-freedom controller which allows one to shape reference and disturbance responses separately. Subsequently, the two-degree-of-freedom controller, which proves to be superior, is adapted to the nonlinear framework by considering a linear parameter varying representation of the nonlinear plant. Finally, the nonlinear controller is implemented in a test car confirming the concept applicability to real hardware.
Aktywne systemy zawieszenia łagodzą konflikt między komfortem a właściwościami jezdnymi samochodu. Wymagają one użycia odpowiednich siłowników, a te z kolei powinny być efektywnie sterowane. W artykule zaproponowano opartą na modelowaniu koncepcję sterowania nieliniowego siłownika w zawieszeniu samochodu. Koncepcja tego rozwiązania jest początkowo przedstawiona w ramach opisu liniowego, co ma uprościć fazę syntezy i analizy. Na tym etapie jest proponowany i dyskutowany model liniowy. Ta faza projektowania obejmuje ponadto porównanie między niezwiązanymi z modelem sterownikami PID i proponowanym, nowym sterownikiem o dwu stopniach swobody, który pozwala niezależnie kształtować odpowiedź referencyjną i odpowiedź na zakłócenia. W dalszym etapie, dla sterownika o dwu stopniach swobody, który okazał sie lepszy od pozostałych, wprowadza się opis nieliniowy, traktując parametr liniowy jak zmienną reprezentację nieliniowego obiektu regulacji. Ostatecznie, nieliniowy sterownik zawieszenia jest instalowany w samochodzie testowym, a badania potwierdzają celowość zastosowania tej koncepcji w rzeczywistym sprzęcie.

Opis:
This paper investigates the effect of employing an inerter on the performance of active suspension systems. A quarter-car model with cubic-nonlinear spring is considered. The inerter is installed in parallel with the primary suspension spring and damper. First, feedback linearization (FBL) is used to linearize the mathematical model. Then the linear quadratic regulator (LQR) is adopted to control the suspension system. The proposed design is ride comfort-oriented and considers structural constraints. Numerical simulations are executed for passive systems with different values of inertance. Results show that employing an inerter to the passive suspension can improve the ride comfort performance by more than 32%. Employing an inerter to active suspension systems can also improve the ride comfort and reduce actuator force significantly. The actuator force can be reduced by 25%. However, the results also show that the uncaring selection of the inerter can dramatically degrade the performance of the suspension system.

Opis:
Mobile heavy machines produce vibrations with low natural frequencies. Because they tend to ride at low speeds, excitations due to road roughness excite low frequency vibrations, which can be reduced by active or semi active methods only. Under conditions of low frequency vibrations, energy dissipation in tires will reduce the vibration intensity in a minor degree only. In the unsprung mobile machine vibration isolation system are provided between a vibration source and the protected object (operator) along the path of vibration propagation. Most machines are now equipped with controlled suspension seats. In the case of active suspensions, the external energy source is required, for instance in the form of compressed air. The compressed air has the advantage that it is generally available in heavy machines as the working fluid and is environmentally friendly. Simulation tests were carried out both in the time domain in Matlab-Simulink and in the frequency domain in the program Mathcad. Simulation tests were performed to investigate effectiveness and stability of the proposed solution and the results were deemed satisfactory. The system was found to be feasible and implementable with respect to every parameter. The first purpose of this study is to develop a simulation model of the active suspension of operator's seat based on an adjustable pneumatic actuator. The other purpose of this study is to examine the effectiveness of different control strategies.

Opis:
Low-frequency vibrations, generated in mobile machines during their driving, could be reduced only by use of active or semiactive methods. In conditions of low-frequency vibrations, energy dissipation in the machines tires slightly reduces the intensity of the vibration. Unsprung mobile machines are usually equipped with system of vibration isolation, which is located on the way of vibration propagation, between the vibration source and the protected object (the operator of the machine). Generally, controlled seat suspension is used. In the case of the active suspensions, it is necessary to provide external energy, e.g., in the form of compressed air. The compressed air has the advantage that it is generally available in working machines as the working fluid and has its environmentally friendly properties (leaks do not contaminate the environment).

Currently aim of the study was experimental verification of the theoretical results; this verification was performed on the laboratory test bench. In the stand tests, special attention was paid on the assumed models of friction and thermodynamic phenomena in pneumatic actuator, as well as on the control system. Experimental tests were carried out under conditions of harmonic excitations, coming from the electromechanical vibration exciter with controllable pitch and frequency. Data acquisition system and control circuit of the proportional directional control valve, supplying compressed air to the actuator were implemented using Matlab-Simulink Real-Time software. Identification of the simulation model allows for getting the right parameters of the seat suspension. In addition, parametric optimization of the seat suspension system and functional optimization of control strategy would be possible in the next step.

Opis:
Low speeds of mobile heavy machines makes that the force derived from rough roads cause intense excitation of low frequency vibration, the reduction of which is possible only by active or semi active methods. In conditions of low frequency, the energy dissipation in the tire reduces the vibration intensity in a minor degree only magnetorheological dampers are free from this defect, which they properties changing under influence an electric field functioning on ferromagnetic particles of oil suspension. A controlling coil current, which is mounted in the damper piston, could control density of magnetic field lines (magnetic field intensity) directly in viscous hole of piston, and hence viscous drag force. Electric energy needed to control magnetorheological damper is generally available in each of mobile heavy machines. Simulation tests were performed to investigate effectiveness and stability of the proposed solution and the results were deemed satisfactory. The system was found to be feasible and implementable with respect to every parameter. The purpose of this study was to develop a simulation model of the semi active suspensions of operator’s seat based on magnetorheological damper, and to examine the effectiveness of using different control strategies.

Opis:
The paper presents a new control strategy for active vehicle suspensions using electrohydraulic actuators based on Takagi-Sugeno (T-S) fuzzy modelling technique. As the electrohydraulic actuator dynamics is highly nonlinear, the T-S fuzzy modelling technique using the idea of "sector nonlinearity" is applied to exactly represent the nonlinear dynamics of electrohydraulic actuator in a denned region at first. Then, by means of parallel distributed compensation (PDC) scheme and Lyapunov method, a fuzzy HOO controller is designed for the T-S fuzzy model to optimise the suspension ride comfort performance, considering actuator input voltage saturation problem. The sufficient conditions for the existence of such a controller are derived in terms of linear matrix inequalities (LMIs). The advantage of this new control strategy for electro-hydraulic active suspensions is that it directly aims at optimising suspension performance with guaranteeing the closed-loop system stability. Thus, two-loop control strategy, where the inner loop is used to make the electrohydraulic actuator tracking a desired force (pressure, or displacement, etc.), is not necessary. In addition, the controller is simple in structure compared to the adaptive control algorithms. A numerical example is used to validate the effectiveness of the proposed approach. It is confirmed by the simulations that the designed controller can achieve better performance than the active suspension with optimal skyhook damper.

In this paper, analysis of a half-car model with linear and nonlinear semi-active dampers is performed. Using Matlab-Simulink software, a response of the system to a harmonic excitation of variable frequency and to an impulse excitation is found. The effect of both the distribution of spring-supported mass and the asymmetry of the support on the frequency characteristics of velocities and displacements at the mounting points of the dampers are analyzed. Additionally, characteristics of forces generated by the semi-active dampers and the response of the system when crossing an obstacle are determined.

This seat suspension prototype is built with a shear guidance mechanism, an air spring, a hydraulic shock absorber and end-stop buffers. The acceleration particular signals are measured by using Inertial Measurement Units (IMUs) placed on the seat and the human head. As the excitation, the horizontal vibrations are applied. As an alternative to the classical Fourier approach, the Wavelet Transfer Function (WTF) is introduced to describe the effectiveness of particular seat suspension. In both of the system cases, the human head reaction is investigated by using the Matlab package.

Opis:
Zastosowane w samochodach osobowych rozwiązania konstrukcyjne zawieszenia muszą spełniać szereg wymogów, do których należą zapewnienie odpowiedniego komfortu jazdy, czy też bezpiecznego zachowania się samochodu podczas jazdy w różnych warunkach. Niestety część wymogów wyklucza się wzajemnie, dlatego też na świecie trwają ciągłe prace mające na celu opracowanie systemów mogących pogodzić sprzeczne wymagania. Przedstawione w pracy badania miały na celu porównanie poziomu drgań oddziaływujących na kierowcę i pasażerów w trakcie jazdy samochodem osobowym. W badaniach sprawdzano różnicę w odczuwalnym komforcie jazdy samochodem z klasycznym i aktywnym zawieszeniem. Dodatkowo sprawdzano wpływ wybranego trybu działania aktywnego zawieszenia – komfort i sport. Badania przeprowadzono dla różnych prędkości jazdy samochodu poruszającego się po zróżnicowanych nawierzchniach drogi – nawierzchnia asfaltowa, kostka brukowa, betonowe płyty.
Used in cars suspension design solutions must meet a number of requirements, which include providing adequate comfort or safe behavior of the car when driving in different conditions. Unfortunately, part of the requirements is mutually exclusive, which is why the world continues ongoing work to develop systems that could reconcile conflicting demands. The work study was to compare the levels of vibration acting on the driver and passengers in the car during the drive. The study tested noticeable difference in driving comfort of a car with a classic and active suspension. In addition, were checked the effects of the selected operating mode of active suspension – comfort and sport. The study was conducted for various speeds of a moving vehicle on different road surfaces – asphalt, paving stones, concrete slabs.

Opis:
For pursuing high performance, the development of semi-active suspension control tends to be complicated and ignores practicability. A new mixed control method effectively suppressing vibration of the vehicle body in the whole frequency band is proposed based on electromechanical analogy theory. Simulation results show that in comparison with passive suspension, on a long slope bumpy road, the mixed control reduces body acceleration by 21.49% and the maximum amplitude by 22.40%. On a C class road, the mixed control reduces body acceleration by 9.78%. Finally, an ECU hardware-in-the-loop test is conducted, which verifies the effectiveness and feasibility of the new mixed control method.
