摘要
For a load object, the air balance compensated servo electric cylinder is used as the actuator to drive the vertical part to aim target. The nonlinear links in the super load electric cylinder servo system include the trigonometric nonlinear relationship between the pitch angle and the motor angle, the time-varying relationship between the pitch angle and the supporting torque and gravity distance of the electric cylinder, the servo system and other nonlinear links. Simply using the position PID control algorithm can not meet the tracking accuracy requirements of the system. By using the fuzzy PID control algorithm with nonlinear compensation, the tracking accuracy problem in the servo system can be effectively solved. The fuzzy PID control algorithm with nonlinear feedforward compensation is designed. The simulation and test results show that the method effectively improves the servo control accuracy.
