An integrated simulation and development environment for the digital controlled AC servo system is proposed in this paper, which is based on personal computer to be applied to simulate, optimize and adjust the control code, control parameters and control models of system without any hardware. It's an exploration for improving the digital controlled AC servo system's developing condition. Realization of this method will greatly reduce the time and cost in developing servo system and improve the
