Abstract

Permanent Magnet Synchronous Motor (PMSM) has been widely used in many fields for its advantages of small size, high efficiency, simple structure and low noise. In order to further improve performance of PMSM, it is necessary to do further research of its control strategy. Therefore, this paper mainly studied the direct torque control (DTC) strategy and its improved algorithm of PMSM. In this paper, we first introduce the mathematical model of PMSM and the zero vectors DTC, and then compares the traditional PID controller and the new adaptive PID controller. In order to better explain the problem, this paper makes a comparative simulation of the traditional DTC and the zero vectors DTC and the simulation results are shown in figure 1-8. By analyzing the results, we can find that the simulation that the flux waveform, three phase current waveform, the electromagnetic torque waveform, the speed waveform and the pulse of the DTC control with zero vectors have been improved obviously. In response time, the two can respond more quickly. So, this fully proves the superiority of the zero vector DTC control. And at the same time, we make a comparative simulation of the traditional PID control and the new PID control, and the simulation results are shown in figure 8- Figure 11. By analyzing and comparing the simulation results, we can find that the torque and speed pulse of the new adaptive PID controller is smaller, and its response time is shorter, and its anti-interference ability is stronger, and the steady state performance of the motor is improved remarkably.
