The strap-down stabilization platform as the research object, the composition and working principle of two axis stabilized platform are introduced. The mathematical model of the closed-loop control system is established, and the PID control algorithm is based on the system. In order to improve the response speed and tracking accuracy, a feed-forward control algorithm based on angle and angular acceleration compensation is introduced. The stable platform for the feed-forward compensation control algorithm is verified by the experiment, the feed-forward control used in strapdown stabilization platform can improve the response speed and tracking accuracy of the system, meeting the requirements of the task.
