Abstract
Control algorithm is the core of AC servo system. In order to improve the performance of system, on the basis of vector control system and space vector pulse width modulation (SVPWM), inverse matrix and projection of out U on plane rectangular coordinate system were used to determine the nonzero vector movement time 2 1 t t、 . Then, a calcula- tion method of vector switch point T cm1 ,T cm2 ,T cm3 was given. Finally, a judgment method of sector which vector locate was given based on the one-to-one relationship between index number and sector. Simulation was carried on and some simulation results show that the system has good dynamic response and steady-state accuracy.
