基于MRAS内置式永磁同步电机无位置传感器控制研究
Research of Interior Permanent Magnet Synchronous Motor Sensorless Control Based on MRAS
摘要
Abstract
One novel control strategy for IPMSM sensorless control based on MRAS was presented. This control strategy can estimate the rotor speed with a few parameters. IPMSM itself was selected as reference model, and the mathematical model of IPMSM which includes estimated parameters was regarded as adaptive model. The output error of these two models was used to drive the adaption mechanism and the estimated speed was obtained. Also the PI control in MRAS to increase the dynamic performance was introduced. Using this control strategy, IPMSM could work under very low speed condition of 0. 5 Hz. The simulation results verify the proposed control strategy was effective, it had excellent dynamic and static responses, the estimated speed had good precision and the system was robust and could still work well in the very low speed range.关键词
