矩阵变换器驱动永磁同步电机的模型预测转矩控制
Model predictive torque control of permanent magnet synchronous motor system driven by matrix converter
摘要
Abstract
Employing matrix converter (MC)as driving mode,the strategy of model predictive torque control (MPTC)is proposed for three-phase permanent magnet synchronous motor (PMSM)system.MC is applied instead of conventional AC-DC-AC converter to increase the power factor (PF)of the system input side.MPTC is used to select optimal voltage space vector to enable the system to have satisfactory torque and flux control effect.The resultant MPTC strategy not only makes the MC-fed PMSM system operate reliably and have perfect control performance,but also makes the PF of the system input side be 1.Compared with direct torque control (DTC),the proposed MPTC strategy guarantees that MC-fed PMSM has better command-following characteristics in the presence of variation of load torque and tracking reference speed.Simulation results verify the feasibility and effectiveness of the proposed strategy.关键词
