DESIGN OF AUTOPILOT ON A MISSILE WITH A GENERAL ADAPTIVE CONTROL STRUCTURE

Design of the missile autopilot is a key in making the missile to possess high hit precision. A general adaptive control structure is applied in designing the missile autopilot. A damping inner loop and an accelerating outer loop of the pitch channel for the missile autopilot are designed by an adaptive generalized predictive control (AGPC) algorithm to make the missile offer relevant acceleration rapidly according to instructions for guidance. It is proved from the results of system math simulation carried out under some typical conditions, that the designed control algorithm can control the missile to attack the target satisfying the tactical requests. Furthermore, it is restrained from some uncertain disturbances such as un model dynamics, aerodynamics parameters dispersions and noise.
