We have developed a simulation model of homing-guided anti-aircraft or surface-to air (SA) missiles – SAM, suitable for research, development and testing of different guidance and control laws, obtained from synthesis process. This system was developed for the teaching and training purposes of several subjects at Macedonian Military Academy. The topics in External ballistics give cadets knowledge in guided missiles movement, which are considered as dynamic systems and controlled objects. In homing-guidance systems for SA missiles – proportional navigation is most commonly used, and also improved solutions and optimal guidance laws based on modern control theory. All systems for guidance and control of SA missiles are complex and typically non-linear. In order to provide quality process and small guidance error – we have applied fuzzy logic to obtain some parameters for the guidance law. In this paper we present results from investigation of different guidance laws for hypothetic SA missile. The results from fuzzy guidance law combined with proportional navigation are also given. Simulation programs are realized in MATLAB/SIMULINK. |
