异步电机模型预测直接转矩控制
Model Predictive Direct Torque Control of Asynchronous Motor
摘要
Abstract
There is a large amount of calculation during the traditional model predictive direct torque control ( MPDTC) process which leads to the time delay and hinder the application of the MPDTC. In order to solve the problem, presents a novel model predictive direct torque control method based on objective function optimization. A delay compensation-based model predictive control strategy was derived by combining the Lagrange extrapolation and the prediction of the stator flux linkage and torque. Based on three-phase voltage inverter driven induction motor, we established the simulation model of MPDTC. Simulation results showed that the algorithm could effectively reduce the torque and flux ripple and reduce the current harmonics distortion with high dynamic response. Especially, the proposed method could solve the delay problem in traditional method. Simulation results were given to show the effective of the proposed method.关键词
