Fault Tolerant Control Strategy for Permanent Magnet Synchronous Motor Based on Higher Order Sliding Mode Observer
摘要
Abstract
Aiming at electric vehicle safe driving problem,a fault tolerant control strategy for PMSM of the electric vehicle based on higher order sliding mode observer was proposed. The high-order sliding mode observer was designed based on the model of the PMSM,and the convergence of the observer was proved. Then,the fault tolerant controller of PMSM drive system was designed based on the sensor fault model ,the high order sliding mode observer and the reconfiguration strategy. Finally,some experiments were carried out based on a small power PMSM test platform. The test results verify the effectiveness of the new control strategy.关键词
