Fuzzy + PID variable sliding mode control for servo plat

Based on a servo actuator system with the platform, tracking control problem of the platform is discussed in the research, and put forward a kind of fuzzy + PID variable sliding mode switching-control method which makes the system fast and stably track the target. Through the brush DC position servo system of mathematical modeling and load information analysis and platform position of the signal detection, we design a Fuzzy + PID variable sliding mode tracking controller, and the controller according to Hyper plane function _S(_x) switches in two control ways. Finally simulation experiments are conducted based on simulink. The result shows that the controller can solve the problem of the system tracking speed and tracking accuracy in a better way.
