摘　　要：以面贴式三相永磁同步电机(PMSM)为研究对象,研究基于递推最小二乘法和模型参考自适应法的混合多模型在线辨识方案,通过指标函数实时优化动态模型库。在电机运行过程中,根据"优胜、劣汰"规则匹配调节器模型和参数,提出基于混合多模型控制的永磁同步电机在线控制策略,达到在线整定参数的目的。将混合多模型策略应用于PMSM调速系统测试平台,仿真和试验结果验证了所提方案的可行性和混合多模型控制策略的正确性。Taking the stick-type three-phase permanent magnet synchronous motor(PMSM)as the researchobject,studied the hybrid multiple model online identification scheme based on the recursive least squares estimation(RLSE)method and model reference adaptive system(MRAS)method. Dynamic model library was optimizedreal-time by index function. A control system based on hybrid multi-mode library was proposed and the parameterswere adjusted online according to the rule'superior win,bad discard'. The hybrid multi model strategy was appliedto the PMSM speed control system. The simulation and experimental results verify the feasibility and correctness ofthe proposed scheme.
