永磁同步电机模型预测电流控制精简控制集策略
Streamlined control set strategies of model predictive current control for permanent magnet synchronous motor
摘要
Abstract
The model predictive current control(MPCC)for both surface-mounted permanent magnet synchronous motors(SPMSM)and interior permanent magnet synchronous motors(IPMSM)using a conventional control set requires enumerating all seven basic voltage vectors in the prediction process,which causes large computational burden and poor real-time performance.To address this issue,three streamlined control sets are proposed by adding constraints.Based on the signs of the errors between the dq-axis reference currents and the actual currents,as well as the signs of the dq-axis components of the seven basic voltage vectors,the utilization rates of the voltage vectors are analyzed by adding constraints.By discarding vectors with low utilization,two streamlined control sets are proposed.Furthermore,an additional constraint based on the square root of the dq-axis current errors is added to further simplify the control set.The results of simulation and real-time experiments of SPMSM and IPMSM show that the performance of the streamlined control set I is exactly the same as that of the traditional control set and it can reduce at least 1 traversal;the performance of streamlined control set Ⅱ and streamlined control set Ⅲ is comparable to that of the traditional control set and the traversal calculations can be reduced by at least 4 and 5 times,respectively.关键词
