Robust PID autopilot design for back-to-tum missile

摘要

This paper presents a robust proportional-integral-derivative (PID) control autopilot design method for the BTT (Back-to-turn) missile. Robust PID control scheme is designed to stabilize the three channels and to compensate the lumped disturbances consisting of non-linear couplings and external disturbances. The robust PID control parameters are obtained using Kharitnov theorem and control scheme is designed separately for the each subsystem. The effect of proposed control demonstrated with simulation results in the presence of external, disturbances, non-linear couplings, and parameter perturbations.
