Opis:: The article presents the results of numerical simulation of a laser-guided bomb, which is dropped in calm weather conditions. The prototype of such a bomb was developed at the Air Force Institute of Technology. It was a result of the modification process of the classical training bomb. The modification consisted of building on the bomb's board a detection system to track targets that are designated by laser and a control system to adjust bomb’s glide path to precisely strike the target. In the simulation research, geometric and mass characteristics of the classical training bomb were used. Aerodynamic characteristics of the bomb have been determined using commercial software PRODAS. Using the mathematical model of the bomb spatial motion and model of the laser detection system series of simulations were performed. The main goal was to determine the effectiveness of the adopted construction solution. Therefore, simulations were performed for various initial positions of the bomb and fixed position of the target. It allowed finding the set of control laws coefficients giving the most accuracy of the bomb. The influence of structural modifications of the detection system on the possibility of effective detection and location of the target was also investigated. In the article, exemplary results of numerical calculations performed with the author's software are also shown.

Opis:: Hydrostatic drive systems with linear actuators are commonly used in variety of mobile machines and vehicles. One of important aspect of its operation is cylinder velocity control in variable operating conditions, such as different load, pump pressure and engine rotational velocity. The aim of this article is to create an algorithm, which would control velocity of a hydraulic cylinder used in such systems. One way to create cylinder velocity control system is to perform an identification, which would characterize this system. To do this work it was appropriate to use test stand with excavator equipment. The first part of the article includes the description of the stand and enumerates parts that compose it. Correct work of the control system is possible through use of a proper controller. For achieving a desired purpose, a PID controller was used with some modifications improving system's operation. The controller parameters were tuned based on the model of the system, obtained on the basis of estimation, for different operational conditions. To do this, a tool of MATLAB Simulink called Parameter Estimation was used. The control algorithm, in automatic mode, makes system tuning based on coefficients array. The final stage of the research work was to conduct verification tests, which let to assess a correctness of the created and proposed control system.

Opis:: This article presents the process of designing a fuzzy logic controller (FLC) to be applied in the control system for the tracking movement of an omnidirectional Mecanum-wheeled platform, where the tracking movement is defined as the execution of a specific movement of the omnidirectional Mecanum-wheeled platform along a preset path. The conventional PID controller, which is a popular choice for control systems, was replaced with a control algorithm featuring fuzzy logic elements. The findings from numerical testing of the control system with the applied FLC were compared with the results of numerical testing using a variant of a conventional PID controller. The comparison led to a feasibility study of the FLC for the kinematic control of the omnidirectional Mecanum-wheeled platform. The article compares the results of applying an FLC and a variant of a conventional PID controller for the tracking control of an omnidirectional-wheeled platform with mecanum wheels. It was assumed in this work that kinematic equations would be sufficient in this case to plan the trajectory (path) of a characteristic point for the omnidirectional-wheeled platform.
