异步电机低开关损耗的模型预测直接转矩控制
Model Predictive Direct Torque Control for Low Switching Losses Control of Induction Motor
摘要
Abstract
A novel induction motor low switching loss model predictive direct torque control (MPDTC)is proposed in this paper. By building the discrete time prediction model of an induction motor and extrapolation the output vector trajectory with different switch vector, a plurality of long range output trajectory are obtained. The switching losses of three-level inverter generated during switching are analyzed, and by using the average switching losses of the inverter as an evaluation function to evaluate the output trajectory, the optimum switching vector is obtained. The optimum switching vector is used to the inverter, thus the inverter switching losses is reduced effectively. The simulation results show that the driving system based on the control scheme has low inverter switching losses and excellent static and dynamic performance of torque and flux linkage.关键词
