Huazhong Xu, Jinquan He, Chang-Zhe Chen · 2009
A vector control strategy of PMSM based on Pan-Boolean algebra self-adapting PID control is proposed in this paper, which is unnecessary to set up the exact mathematical model of the controlled plant. According to the deviation and deviation rate at different time, it is able to eliminate the influences of the parameters of the controlled plant and the disturbance of the external environment by online adjusting the parameters of the PID controller. For the PMSM speed adjustment system, the PI controller is used in current loop and Pan-Boolean algebra self-adjusting PID controller is used in speed loop instead of traditional PI controller. The effectiveness of the proposed control method is verified by simulation based on Matlab and implemented using experimental platform based on DSP chip. The simulation and experimental results show that the performance and robustness of the controller are better than the conventional PI controller in the PMSM control system.
