Abstract
Aiming at the speed control of hydrostatic transmission system, a design method of adaptive fuzzy sliding mode control with friction torque dynamic compensation is proposed. 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 parameters and external disturbances of the system, so that the design of controller can be performed without accurate model. The adaptive law derived by Lyapunov method can guarantee the stability of control system and reduce 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.
