摘要
Abstract
The high harmonic and buffeting problem exist in traditional sliding mode observers,which could not meet system requirements of high dynamic control.To overcome this problem,an improved shding mode observer with estimated back-EMF(electromotive force) feeding back to the calculation of stator current observation,extended Kalman filter and saturation function were designed and implemented.The experimental results show that the improved sliding mode observer can significantly weaken the negative impact of buffeting problem and higher harmonic and can obtain a perfect performance of dynamic tracking and a nice robustness.The Matlab simulation and DSP experimental results verify the availability of the improved sliding mode observer.关键词
