基于滑模观测器的感应电机模型预测转矩控制
Model Predictive Torque Control for Induction Motor Based on Sliding Mode Observer
摘要
Abstract
In order to improve the performance of the induction motor(IM)driving system,a sliding mode observer-based model predictive torque control(PTC)strategy for IM driving system was designed. The model reference adaptive system(MRAS)can accurately estimate the rotor speed,but the speed sensorless PTC scheme not only needs to estimate the rotor speed,but also needs to estimate the flux linkage. Therefore,the sliding mode observer was used as a reference model in the MRAS. At the same time,the chattering problem of the sliding mode method was solved by optimizing the sliding function and designing an appropriate gain through the H∞method. The test results show that the new scheme can be implemented stably in a wide speed range with better load performance,and also has the advantages of dynamic swiftness,simple structure and easy implementation.关键词
