【Abstract】 A novel high performance AC servo system with permanent magnet synchronous motor (PMSM) using vector control is presented. A 8096 single chip microcomputer is used as the controller and operator. The vector control principle of the PMSM, the realization of the current control for SPWN inverter by quasi-linear decoupling, and a comparison between the AC and DC current control are described. The stability of the servo system, the self-adjustment of the parameter of the speed regulator, the effect of the servo gain on the servo response, and the ways of adjusting the servo gain are discussed from the practical point of view. The hardware of the system proposed is simple and the speed response is quick with a speed range of 1 : 1000.更多还原
