Speed control of sensorless PMSM drive based on EKF optimized by variable scale chaotic particle swarm optimization

To investigate the parameter characteristics of permanent magnet synchronous motor (PMSM) speed sensorless vector control system and capture the noise matrices quickly and accurately in the speed estimation process of the extended Kalman filter for PMSM, The recursive least square method with forgetting factor is proposed to determine the actual parameters of the system, and then a new variable-scale chaotic particle swarm optimization (VCPSO) algorithm is put forward to accurately obtain the system noise matrix and the measurement noise matrix. The simulation results show that noise matrix optimization of extended Kalman filter by employing VCPSO algorithm under actual motor parameters is better than those employing standard PSO or chaotic PSO algorithms with faster speed and higher accuracy.

Sensorless vector control approach for the interior PM synchronous machine with DC-offset compensation loop

Two different DC offset compensators for sensorless PMSM, motor drives with wide speed range flux linkage observers, are introduced and compared. The first one is an improved flux observer with PI correction and no need for mover speed and phase adaptation. The second one is a novel flux observer with an active disturbance rejection controller (ADRC) compensator without mover speed adaptation. The ESO built into ADRC is able to detect and compensate for both internal model disturbance and external load disturbance, resulting in a controller with superior dynamic responsiveness and robust regulation. In both scenarios, an injected direct current (DC) offset is calculated and maintained by the PI integral part and ADRC, which effectively compensates for the DC biases and drifts caused by the sampling channels. Compared to the PI controller, ADRC demonstrates greater transient performance and disturbance robustness. The results of theoretical analysis and Matlab simulations have confirmed the feasibility and efficiency of the proposed strategy.
