【Abstract】 Based on the research on mathematic model of permanent magnet synchronous motor(PMSM) and direct torque control(DTC) theory,a fully digital AC servo motion controller for X-Y table using single DSP is proposed.This system takes the advanced motor control chip TMS320F2812 as its core,and makes the best use of its port sources and rapid computation capability.Meanwhile,it integrated DTC’s excellent features of simplicity in structure,low-dependency on system parameters and good dynamic response,which greatly reduces the volume and cost of the entire system while increases robustness.Experimental design shows that this system has good control performance.更多还原
