Adaptive Fuzzy Sliding-Mode Control for Direct Drive Electro-Hydraulic Servo Rocket Rudder

摘要：

Aiming at the rapidity control problem of Direct Drive Electro-Hydraulic (DDEH) servo Rocket Rudder, a design method of adaptive fuzzy sliding mode control with friction torque dynamic compensation is presented. The friction torque dynamic compensation method is introduced to enhance the response of the system. The adaptive fuzzy controller is introduced to solve the problem of the uncertain parameter and external disturbances of the system, so the controller can be designed without accurate model. The adaptive law, which is derived of Lyapunov method, guarantees the stability of control system, reduces the high frequency chattering. Simulation results show that the control approach can decrease the tracking error, enhance the system’s robustness and attenuate the high frequency chattering in the control signal.
