一种新型无速度传感器矢量控制PMSM系统
A new speed sensorless vector control system of permanent magnet synchronous motors
摘要
Abstract
In view of speed estimation and the variation of motor stator resistance, according to the principle of the model reference adaptive system ( MRAS), the estimation methods for the rotor speed and stator resistance are derived in the synchronous rotating coordinate system. The mathematical model of speed sensorless vector control system of permanent magnet synchronous motors (PMSM) with stator resistance on-line identification is established. By simplifying the control system, the transfer function of current regulator and speed regulator of the proposed system are determined, and the control gains of current regulator and speed regulator have been designed. The simulation results indicate that the system robustness is good for the stator resistance variation, the speed estimation and control have a high precision, and the system is feasible.关键词
