The software and hardware of a digital AC servo system using a digitalcontroller DMC300A as the control center is designed. This method to obtain some important parameters is proposed.
Because of the essence of this control system is to complete servo cylinder test, we adopted many control strategies, and the design of digitalcontroller of computer is the main research object.
Applied the embedded digitalcontroller, the hydraulic servo actuator has the function of flexible setting and intelligent control. The digitization of hydraulic servo actuator has been achieved.
