Opis:: The paper deals with the control design of semi-active seat suspension systems. A semi-active vibration control strategy basing on the inverse dynamics of a spring or damper element and a primary controller is studied. The optimisation procedure proposed in the paper makes it possible to calculate controller settings and these, in turn, to define vibroisolation properties of semi-active suspension systems.
W pracy przedstawiono sposób projektowania systemu sterowania semi-aktywnym układem zawieszenia siedziska. Analizowano algorytm sterowania semi-aktywnego, który bazuje na modelu odwrotnym elementu sprężystego lub tłumiącego oraz na kontrolerze głównym. Procedura optymalizacji zaproponowana w pracy dodatkowo wspomaga dobór nastaw regulatora, ktore to nastawy definiują właściwości wibroizolacyjne semi-aktywnego układu zawieszenia.

Opis:: To analyze the variation rule of the critical instability time-delay of the semi-active ISD suspension, a general solution was proposed and applied into two three-element-structure ISD suspensions. The dynamical response and the performance of the semi-active ISD suspension in various time-delays indicated that different structures had different suspension performance. The time-delay deteriorated the performance of all of the suspensions which were analyzed. The stability of the semi-active ISD suspension would seriously weaken with the critical time-delay. This paper provided a general solution for parameters selection in semi-active ISD suspension design to avoid the negative effect of the time-delay.

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.

Opis:: In this paper, an analysis is performed on a quarter-car model of car suspension with semi- -active and active damper utilizing the sliding mode (SMC) and linear-quadratic control (LQR). The effect of control parameters and time delays in the transmission of control signal on the factors related to the safety and comfort of driving is investigated. The results obtained from numerical simulations are shown in form of frequency characteristics for several selected performance factors.

Opis:: 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.
