PMSM自适应观测器算法低速稳定性研究
Low Speed Stability Research of Adaptive Observer for PMSM
摘要
Abstract
In the speed-sensorless permanent magnet synchronous motor drive system adopting the adaptive observer method,the problem of instability in the low-speed electric mode according to the observer linearization method was analyzed.To solve the problem,the observer augmented with a signal injection technique was researched.The simulation results show that the method is effective to enhance the system parameter robustness and speed observation precision,improve low-speed performance of the speed-sensorless vector control system.关键词
