| Abstract: | Aiming at sensorless vector control system of maximum ratio of torque to current for PMSM,the system model of sensorless control for PMSM of maximum ratio of torque to current was established,which is based on model reference adaptive system.This self-equation of PMSM is selected as the reference model and its corresponding current model as the adjustable model.Under the condition of the same input,the output errors between reference model and adjustable model is adjusted to zero in accordance with appropriate adaptive rate,meanwhile,the parameters of the adjustable model is adjusted real-timely.Simulation analysis and experimental results show that the proposed method has less error and higher precision,good dynamic performance. |
