基于简化有限集模型预测电流控制的五相PMSM统一容错控制
A Unified Fault-tolerant Control of Five-phase PMSM Based on Simplified Finite Control Set Model Predictive Current Control
摘要
Abstract
Five-phase permanent-magnet synchronous motor(PMSM)with finite set model predictive fault-tolerant control(FCS-MPFTC)has large computational complexity and high harmonic currents.Therefore,this paper proposes a simplified FCS-MPFTC strategy to achieve unified fault-tolerant control under open-circuit and short-circuit fault conditions.First,the current cost function of the model predicted current control is equivalently transformed into a voltage cost function,and reference voltages are calculated by the current model with the deadbeat method.Then,virtual voltage vectors(V3)are synthesized based on restraining the third harmonic current to zero.By reconstructing V3 and sectors,the optimal voltage vector corresponding to the reference voltage vector can be directly obtained.Finally,the experimental results of traditional and simplified FCS-MPFTC are presented to demonstrate the effectiveness of the proposed strategy.关键词
