The nonlinearity simulation study on Electrical Hydrostatic Actuator

This paper introduces a new type of actuator, namely Electro-Hydrostatic Actuator (EHA)
^[1]
. According to the engineering, we choose the asymmetric hydraulic cylinder, establish the mathematical model of permanent magnet synchronous motor and EHA, and adopt the MATLAB proceeds to imitate the true research. To solve the problem of nonlinear system, we adopt PID control method.
