Fuzzy control in the DC motor servo system for gravimeter stabilized platform

As a rapid servo control system, the gyro stabilized platform has been used for the gravimeter horizontal stabilization. For a double-shaft stabilized platform droved by the DC torque motor, focusing on the problems of control precision and response speed using classical PID algorithm, this paper has presented a fuzzy control scheme. Firstly, model of the stabilization loop is carried on, then introduces fuzzy control strategy to the double closed loop system, and lastly conducts a simulation to the control system. The performances show the control scheme has improved the response speed and precision, especially the ability of anti-interference has been increased largely.
