OPTIMIZATION OF MISSILE AUTOPILOT GAIN UNDER CROSSOVER FREQUENCY CONSTRAINT

Commands, so the autopilot gain design should be evaluated directly according to the resultant tracking performance. For this purpose, an optimal methodology is proposed for designing an autopilot based on constraint optimization technique, where the tracking performance is established analytically and is an evaluation criterion. The crossover frequency is formed as a function of the restriction in the form of an inequality. The proposed method is implemented with the assistance of a numerical optimization algorithm which automatically adjusts the design parameters. Finally, the results of numerical modeling are presented to demonstrate the effectiveness and feasibility of the proposed approach as compared with that in some references.
