A new method of simulation and development for digital controlled AC servo system

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 and control parameters of system without any hardware. It's an exploration for improving the digital controlled AC servo system's developing condition. In this paper, the arithmetic of RPN and Runge-Kutta are introduced in detail. And then, the validity and the feasibility of environment are verified by simulation and experimental results. Also, through combining exhaust algorithm with the closed-loop simulation environment, parameter optimization can be implemented. In this paper, proportion coefficient and integral time constant of PID control are optimized and good performance is achieved.
