Abstract:

In this work, fuzzy and FMRLC adaptive fuzzy controller schemes are designed and tested practically as position controllers for simple TV-tracking algorithm of fire control system. The designed system is used for detecting and tracking air targets in one-dimension. The system is implemented using hardware circuitry involving both analog and digital circuits. The tracking technique that is proposed in this work is based on image processing functions in which the image frames are analyzed for target checking and difference error correction angle generation. The mathematical analysis of the TV-tracking function is derived and discussed. The simulation design procedure of the two types of the controller and of the TV-tracking algorithm are proposed and tested before applying to the practical and through the simulation of the system the robustness points are discussed. The practical design and implementation procedure of the system hardware, software, interfacing and electronic support are described with their requirements. The performance of the different controllers is tested practically under different conditions. It is found that the adaptive fuzzy controller scheme is better than the fuzzy controller scheme and can be used for the TV-tracking algorithm for fire control system because the system response with adaptive fuzzy controller will be fast, smooth and has zero steady state error. Also it is found that in the case of adaptive fuzzy controller the TV-tracking system can track targets with higher velocity than in the case of using fuzzy logic controller only.
