基于改进型龙贝格观测器PMSM的无传感器控制
Sensorless Control of PMSM Based on Improved Luenberger Observer
摘要
Abstract
When the traditional sensorless control system of salient-pole permanent magnet synchronous mo-tors builds a state observer model in a two-phase stationary coordinate system and uses the equivalent inductance of the stator to convert the inductance of the commutative axis,there is a large error,which affects the sensorless con-trol effect.A sensorless control method based on the Lunberg observer in a two-phase rotating coordinate system is proposed,and the state observer model based on the Lunberg observer is analyzed and established.The prior rota-tional speed is estimated through the q-axis state observer,and the estimated rotational speed is obtained by com-pensating the prior rotational speed with the d-axis state observer.The system is built and tested to verify the rotor information estimation effect of the proposed algorithm.The results show that compared with the traditional rotor in-formation estimation method based on the Lunberg observer,the system adopting the improved Lunberg observer has a faster response speed,higher estimation accuracy,better dynamic performance and steady-state performance,and superior load disturbance resistance performance.Improve the tracking control performance and robustness of the sensorless control system.关键词
