Linear servo motor control method for numerically-controlled machine tool driving

The invention discloses a linear servo motor control method for numerically-controlled machine tool driving. According to the method, a sine wave linear motor is controlled through a feedback signal detection module, a position control ring, a speed control ring and a current control ring, and the feedback signal detection module comprises a position detection module, a speed detection module and a current detection module, wherein the position control ring adopts a composite control method combining PI (proportional-integral) feedback control and neural network given compensation control, the speed control ring adopts a fuzzy controller with a disturbance observer, and the current control ring adopts a space vector PWM (pulse-width modulation) technology with a PI regulator. The linear servo motor control method has the advantages that the neural network compensation PI control technology, the fuzzy control and the alternating current motor vector control are combined, and the anti-jamming capability, the dynamic response capability and the system stable state precision of a linear servo motor are improved.
