| 摘 要： | 以效率优化作为内置式永磁同步电机(IPMSM)驱动系统控制目标,研究了IPMSM的最大转矩电流比控制(MTPA)系统,并分析了MTPA控制的不足。在传统效率优化控制算法基础上充分考虑分析铜耗、铁耗和杂散损耗影响,并考虑参数变化的二次补偿,提出新的损耗最小化控制策略,并对其实际应用进行了工程化简,兼顾了效率优化精度和工程实现性。采用MATLAB软件建立了系统仿真模型,分析对比了以上两种控制策略效率优化效果,仿真结果证明了该策略的有效性。

| Abstract: | The paper which was focus on the efficiency-optimization of IPMSM drive system studied the MTPA system and analyzed the drawbacks of the MTPA. Based on the traditional efficiency-optimization algorithm, a novel LMC control strategy was proposed that the effect of copper loss, iron loss and stray loss and the second compensation for parameter variation were fully considered. To met the efficiency-optimization accuracy and engineering realizable, the engineering simplification were done in practical application. The simulation model of system with MATLAB was established, the performance of two kinds control strategy were compared and analyzed, the simulation results demonstrate the feasibility of the control strategy. |
