Opis:
In the near future, vehicles will be moving autonomously with little participation or completely without the driver affecting on the vehicle move. Task of driver will be limited to identify the end point of the vehicle route. Vehicles, to meet this challenge, must be equipped with the control systems and supervising the movement of the vehicle, reacting onto the movement of pedestrians and other vehicles, road signs, time of day and weather conditions. The movement of the vehicle will be controlled and driven by a system on board a vehicle, but will also be required to tracking the vehicles position and its movement parameters using of the vehicle satellite navigation systems. In addition, the motion trajectory of the vehicle will be determined and any deviation from the target track will be corrected. The article presents a proposal for determining the trajectory of the vehicle based on the control points specified by the coordinates of the location of the vehicle and ways of correcting the trajectory of the vehicle. For this purpose was utilized the vehicle in scale.

Opis:
The article deals with studying the hydrodynamic characteristics of the fluidized bed in gravitation shelf dryers. The algorithm to calculate hydrodynamic characteristics of the fluidized bed in the dryer’s workspace is described. Every block of the algorithm has a primary hydrodynamic characteristics theoretical model of calculation. Principles of disperse phase motion in various areas in the gravitation shelf dryer are established. The software realization of the author’s mathematic model to calculate disperse phase motion trajectory in a free and constrained regime, disperse phase residence time in the dryers’ workspace, polydisperse systems classification is proposed in the study. Calculations of disperse phase motion hydrodynamic characteristics using the software product ANSYS CFX, based on the author’s mathematic model, are presented in the article. The software product enables automating calculation simultaneously by several optimization criteria and visualizing calculation results in the form of 3D images. The disperse phase flow velocity fields are obtained; principles of a wide fraction of the disperse phase distribution in the workspace of the shelf dryer are fixed. The way to define disperse phase residence time91 in the workspace of the shelf dryer in free (without consideration of cooperation with other particles and dryer’s elements) and con-strained motion regimes is proposed in the research. The calculation results make a base for the optimal choice of the gravitation shelf dryer working chamber sizes.

Opis:
In this paper there is described the using of 2D robot workspace analysis method with smoothing process by using B-Spline curves [7]. The robot workspace analysis is necessary to generate the collision-free movement paths. This paper is connected with a project, which will be ended with fully functional added application in robot off-line programming. In the last part of this project the authors created the motion planner based on grading function and Markov chains. This planner allows determining the collision-free trajectory of robot bunch. Determining the collision-free trajectory generates a lot of step functions – all movements were possible in only one direction (parallel to Cartesian axes) [1,7]. The worked out planner choose the best path – by shortest movement length or shortest movement time criterion. Achieved path is optimised and smooth by using NURBS and B-Spline curves [2,4,5], which is the main goal of this paper. Smoothing and time-function making is very important, because it allows getting the speed and acceleration data, which are necessary in robot controlling. B-Spline curves fulfil continuous first and second derivate condition. Another advantage of using B-Spline is a possibility to enlarge the movement quality by using the minimal acceleration criteria. This allows growing the steadiness of movement.

Opis:
This paper presents the application of the reinforcement learning algorithms to the task of autonomous determination of the ship trajectory during thein-harbour and harbour approaching manoeuvres. Authors used Markov decision processes formalism to build up the background of algorithm presentation. Two versions of RL algorithms were tested in the simulations: discrete (Q-learning) and continuous form (Least-Squares Policy Iteration). The results show that in both cases ship trajectory can be found. However discrete Q-learning algorithm suffered from many limitations (mainly curse of dimensionality) and practically is not applicable to the examined task. On the other hand, LSPI gave promising results. To be fully operational, proposed solution should be extended by taking into account ship heading and velocity and coupling with advanced multi-variable controller.

Opis:
Avariety of approaches for trajectory tracking control of wheeled mobile robots have been implemented. This paper presents a model for a time optimal motion control based on fuzzy logic algorithm for a three wheeled nonholonomic mobile robot with desired function. Simplified kinematic equations of a differentially driven robot are designed to follow the path with evaluated linear and angular velocities. Here, the proposed kinematic model is based on a simple geometric approach for getting the desired position and orientation. The speeds are varied depending on the variations in the path and on the posture of the robot. The robot is subjected to move in a constrained workspace. The control architecture was developed based on fuzzy logic algorithm to obtain time optimal motion control of robot trajectory tracking. The kinematic model was done on Matlab software environment and profound impact on the ability of the nonholonomic mobile robot to track the path was evaluated.

Opis:
All physical processes are deterministic de iure. Physicists speak about different types of determinism of physical processes, depending on the degree with which their course can be anticipated. Usually, the course of ergodic processes can be predicted with less certainty than the non-ergodic ones, the latter being integrable. Recent measurements of motions of single particles in composite systems, especially in living biological cells, show that such motions are, in most cases, breaking the Boltzmann’s ergodic hypothesis. On the other hand, their trajectories are random, i.e., one cannot know a priori where the particle will be even in near future. This leads to conclusion that many existing in nature processes are nonergodic but not integrable, therefore predictable only in the mean, representing still other type of determinism.

Opis:
The main objective of this article is to obtain equations of motion of the spin–stabilized projectile in the presence of non–constant wind. Introducing models allowing utilization of inhomogeneous wind is dictated by new possibilities created by the use of e.g. lidars in the Fire Control Systems (FCS). Constant feed of wind data can replace meteorological messages, increasing the FCS effectiveness. Article contains results of projectile flight simulations which indicate the positive effect that the derived explicit form of the model has when considering software development for modern Fire Control Systems.

Opis:
Praca prezentuje alternatywne podejście do konstrukcji zadajnika trajektorii robota chirurgicznego, polegające na wykorzystaniu sprzężonych sensorów ruchu typu MEMS: kompasu, żyroskopu, akcelerometru. Miniaturowy moduł z tymi układami może być nakładany bezpośrednio na dłoń chirurgaoperatora lub na jego palce. Zaletą takiego zadajnika jest nie tylko niska cena, ale również wysoka funkcjonalność, związana z otwartością na dodawanie nowych modułów programowych. Przykładem wbudowanej funkcji może być generator ścieżki dojścia do pola zabiegu, wykorzystujący wielomiany sklejane w reprezentacji Catmull-Rom. Dodatkowo, zadajnik tego typu jest bardzo mały i łatwy do zastosowania w systemie mobilnym (karetka pogotowia, polowy ambulans wojskowy).
The paper presents an alternative approach to the construction of the surgical robot trajectory haptic console by the use of motion MEMS type sensors: compass, gyro, accelerometer. Miniature module with these elements can be applied directly to the surgeon's hand or can be located on his fingers. The advantage of this device is not only low price, but also a high level of functionality associated with openness to adding new software modules. An example of built-in function can be the generator of a come path to the surgery field by the use of spline polynomials in the Catmull-Rom representation. In addition, the haptic console is very small and easy to use in mobile systems (military field ambulances).

Opis:
This study is devoted to the modeling and control of a 4-wheel, skid-steering mobile platform with coupled side wheels, subject to lateral and longitudinal slips. The dynamics equations of the platform are derived, and 16 variants of motion distinguished. For the variant of motion allowing for all possible slips of the wheels two control problems are addressed: the motion planning problem and the trajectory tracking problem. The former problem is solved by means of a Jacobian motion planning algorithm based on the Endogenous Configuration Space Approach and, complementarily, using the Optimal Control Approach. The Nonlinear Model Predictive Control is applied to the latter problem. Performance of these control algorithms is illustrated by a sort of the parking problem. Significant robustness of the predictive control algorithm against the model uncertainty is revealed.

The paper presents basic principles of a ship’s nondimensional trajectory definition (for arbitrary manoeuvres) by means of drift angle and nondimensional yaw velocity. This enables faster and better tuning of mathematical model of ship manoeuvring motions against the provided full scale sea maneouvring trials (usually in a form of position trajectories) – since it is known the governing, basic factors behind the trajectory. A special focus has been applied to the standard turning circle test.
W pracy dokonano nowatorskiego i kompleksowego ujęcia kinematyki ruchu krzywoliniowego, szczególnie w odniesieniu do bezwymiarowej (mierzonej jednostkami długości statku) trajektorii statku podczas manewru cyrkulacji. Sformułowano analitycznie kształt trajektorii oraz jej ewoluty (położenia środków krzywizny). Ponadto przedstawiono praktyczne znaczenie i możliwości kształtowania trajektorii poprzez dobór parametrów zmian kąta dryfu i bezwymiarowej prędkości kątowej. Pozwala to zredukować problem kształtu trajektorii do dwóch parametrów o bardzo ważnej interpretacji hydrodynamicznej, co ma olbrzymie znaczenie w procesie identyfikacji i/lub walidacji matematycznego modelu manewrowania statku.

Opis:
Various models of a projectile in a resisting medium are used. Some are very simple, like the “point mass trajectory model”, others, like the “rigid body trajectory model”, are complex and hard to use, especially in Fire Control Systems due to the fact of numeric complexity and an excess of less important corrections. There exist intermediate ones - e.g. the “modified point mass trajectory model”, which unfortunately is given by an implicitly defined differential equation as Sec. 1 discusses. The main objective of this paper is to present a way to reformulate the model obtaining an easy to solve explicit system having a reasonable complexity yet not being parameter-overloaded. The final form of the M-model, after being carefully derived in Sec. 2, is presented in Subsec. 2.5.

Opis:
In this paper we describe the creation of a model of the motion of a flying object in a geocentric coordinate system (ECEF - Earth-Centered, Earth-Fixed). Such a model can be used to investigate the accuracy and resistance of radio navigation systems to interference. The essence of the design of the model lies in the mathematical description of the motion of a flying object in a geocentric coordinate system. The flight trajectory of a flying object consists of one straight section and two turns. When creating a model, we assume a flight at a constant altitude. In this paper, we present one of the possible procedures for modelling the motion of a flying object in a geocentric coordinate system. We chose the initial coordinates of the flying object according to flightradar 24. We used the Matlab software for computer simulation.
