Abstract: On basis of the permanent magnet linear synchronous motors dq shaft dynamic mathematical model, and it gave the servo systems control strategy: id=0,flux tracking voltage space vector pulse width modulation ( SVPWM ) control technology, trapezoidal velocity curve, digital PID control algorithm, speed, current sampling by means of digital filtering algorithm. Then the permanent magnetic linear synchronous servo control system’s design and implementation, was built based on DSP and IPM of permanent magnet linear synchronous motor servo control system. Finally, the permanent magnet linear synchronous motor servo control system was carried out on the experimental platform of noload. By analyzing, the experimental results demonstrate the effectiveness of the strategy and the design of the circuit is correct, and the servo system can be stable and reliable operation.
