无差拍优化五相永磁同步电机有限集模型预测转矩控制算法
Finite-control-set Model Predictive Torque Control Algorithm With Deadbeat Optimization for Five-phase Permanent-magnet Synchronous Machines Drives
摘要
Abstract
The favor and attention in multiphase permanent-magnet synchronous machines (PMSM) drives has substantially increased day by day,due to the potential advantages in high-power with low-voltage and high reliability applications.This paper discussed two traditional finite-control-set model predictive torque control (FCS-MPTC) schemes firstly.In these schemes,the third order harmonic items were included in cost function in order to eliminate the low-order current harmonics caused in d3-q3 subspace.And then,a deadbeat predictive FCS-MPTC scheme for five-phase permanent-magnet synchronous motor (PMSM) drives was proposed to optimize the selection process of the best switching vector in every control interval.The proposed algorithm can bring the following benefits:fast control dynamic response,superior steady-state performance and low-order current harmonic reduction.Furthermore,the proposed scheme can relieve the heavy calculation burden in the traditional FCS-MPTC methods,dramatically.The experimental hard-in-loop (HIL) results have verified the correctness and effectiveness of the proposed scheme.关键词
