The Research of Dynamic Characteristics in Stepper Current Control of Permanent Magnet Synchronous Motor
Permanent magnet synchronous motor has a simple structure,wide speed range and good performance. It has been more and more widely used in AC servo control system. In this paper,the method of step current control is used in the research of dynamic characteristics of permanent magnet synchronous motor ,the location,speed,current and other dynamic variables have been analyzed,paper presents the relationship between position and velocity,the method of step controller and current tracking control by the open-loop design. Since multi-level transmission exists in actual suppression weapons drive system .inevitably produces the phenomenon of air back,closed loop design offered a five-section of speed of curves,to solve the deviation generated from the space back in system,to realize the optimal control of the permanent magnet synchronous motor.
