| 摘 要： | 为了进一步提高异步电机的控制性能,减小磁链和电流脉动,针对传统异步电机有限控制集模型预测转矩控制(FCS-MPTC)中目标代价函数权重因子的配置问题,提出一种模糊在线调整权重因子的异步电机FCS-MPTC方法。通过判断转矩和磁链误差,采用Takagi-Sugeno模糊控制方法实现对权重因子的动态调整,并给出了模糊论域和相应的模糊规则设计。同时考虑到三相异步电机驱动系统中逆变器开关故障给控制系统带来的影响,采用三相六开关容错控制策略对系统进行容错控制。仿真结果表明:该控制方法能够平滑磁链和电流输出,减小电流谐波。

| Abstract: | In order to further improve the control performance of asynchronous motor and reduce flux and current ripple, a method of fuzzy online adjusting of weight factor was proposed for the allocation of objective cost function weight factor in traditional finite control set model predictive torque control (FCSMPTC). The TakagiSugeno model fuzzy control method was used to realize the dynamic adjustment of the weighting factor by judging the torque and flux linkage error, and the domain of fuzzy control and its reasoning rule were also built. At the same time, considering the influence of the inverter switch fault on the control system in the threephase asynchronous motor drive system, a threephase sixswitch tolerant control strategy was used as the tolerant control strategy. The simulation results showed that the control method could smooth the flux linkage and current output and reduce the current harmonics. |
