Abstract | ||||
In this paper, lateral beam guidance autopilot system has considered as an aerospace application. The construction and derivation of the equations of motion is considered and partial modification in internal construction of the autopilot has performed. Proposed efficient fuzzy logic and robust compensator control have applied to the lateral beam autopilot system to increase damping oscillation. Moreover, for comparisons the conventional optimal control has designed and evaluated. The robustness and convergence of the system due to the stability derivatives variations are studied. Efficient fuzzy logic control is preferred for this system where, it does not require the complex mathematics associated with conventional control techniques. The digital simulation results show the effectiveness of the proposed fuzzy logic and LQG controllers in terms of fast damping the oscillations, small settling time, and less over/under shoots. | ||||
