Aiming at the problem that changes of nonlinear dynamic resistance of stator affect the performance of speed sensorless vector control system, a hybrid computing intelligence approach is used in the identification of stator resistance of motorized spindle. The partial least squares (PLS) regression is combined with neural network to solve the problem of few samples and multi-correlation of variables in complicated data modeling. The PLS method is used to extract variable components from sample

to the dual PWM converter of abolition DC link, and used space vector modulation to both rectifier link and inverter link which equivalent AC - DC - AC structure, and then back to matrix converter. Hysteresis current tracking method use hysteresis track on the output current to track the reference current.
Motor control strategy has VVVF control, vector control and direct torque control. Through the speed regulator, VVVF control can achieve closed loop of speed; Vector control to achieve
