Design and Optimization of Two-Loop Pilot for Tactical Missile

The specific scheme of two-loop attitude control system was formulated based on the design principle of attitude control system with the damping circuit as the inner loop and the overload control loop as the outer one. As required by the formulated scheme, the damping loop is designed firstly, of which the stability and the dynamic response quality are improved by adjusting the damping coefficient and the addition of the correction network. After that, the design and optimization of the overload control loop are implemented. With the same design method, gain coefficient and correction network are introduced to reduce overshoot of overload response curve, shorten response time and improve efficiency. Besides, the validity of the overload control loop is tested with square wave as input to reflect the real overload command signal.
