The high rolling speed of a missile heavily affects the stabilizing capability of the inertial platform in the laser tracking system (LTS) of the missile. In this paper, a rotational stabilizing platform (RSP) and a fuzzy-PID controller is designed to stabilize the inertial platform. This controller integrates the advantages of both fuzzy controller and classic PID controller. A comparison study is carried out to illustrate the advantages of the proposed fuzzy-PID controller over the classic PID controller. Numerical results indicate that the fuzzy-PID controller outperforms the classic one in effectively handling nonlinear disturbances and quickly stabilizing the inertial platform at the sudden change of missile rolling speed.
