Research on closed-loop simulation system for digital AC servo system

An intelligent and efficient closed-loop simulation system without any hardware is proposed for AC servo system. According to the characteristics of AC servo system and its control processor, the code executing platform combined with the reverse Polish notation algorithm is developed. To gain the accurate simulation results, the discrete motor model and IPM model are built to deal with the dead-time. Based on the simulation system, parameter identification can be implemented and control parameters can be optimized by using the exhaust algorithm. The parameters obtained by the simulation system were successfully applied to an experimental system, and the favorable control performance was achieved.
