摘要：

The structure and working principle of Electro-hydrostatic Actuator was analyzed in this paper. And a mathematical model based on the transfer function was given. The paper analyzed the influence of the electric motor and hydraulic section on the EHA system performance. A nonlinear block diagram model based on the Simulink was established in this paper. A nonlinear PID controller was designed. The simulation results show that the nonlinear PID controller can make the system has better dynamic characteristics than the conventional PID controller.
