From the fundamental equations of AC servo system, using the principle of coordinate transformation of vector a concise mathematical model is deduced, the speed examination arithmetic of PMSM is obtained. The four-times-frequency design of feed-back signal of AC servomotor and the design of speed examination arithmetic of PMSM are completed and the linearity modulation of torque electric current is realized. Through the design and application of digital AC servo system in PMSM, we have reduced the price of cost, improved the control performance of servo system, decreased the times of startup and trig and therefore obtained the upper precision.
