APPLICATION OF ROBUST CONTROLLER TO THE DESIGN OF AUTOPILOT FOR GUIDED MISSLE

In this paper, we develop a new autopilot scheme for guided missile. The scheme dose not change the oringinal structures of the autopilot, only adds a robust controller as an outer loop for the original autopilot. For-this reason, the new scheme is very easy to implement. This new scheme makes the dynamic performance of the flight system insensitive to the variation of the parameters of the guided missile.In this paper, we first verify the existance of the robust controller for the autopilot of the guided missile, and then explain in detail the design method of the servo-compensator and the stabilizing compensator, which are the two main distinct parts of the robust controller for the new-autopilot scheme. The robust properties of the new scheme are also examined by computer simulation, the properties are superior to those of the o-riginal scheme.
