论文摘要
在本文中，提出了针对永久磁铁同步机（PMSM）驱动系统的改进的多步有限控制模型预测电流控制（FCS-MPCC）策略。多步预测机制有益于显着提高电机系统的稳态性能。尽管常规的多步骤预测具有重大计算负担的缺陷，但通过开发新的多步预测机制提出了改进的多步有限控制模型预测电流控制（IM MPCC）策略。此外，为了改善系统的动态响应，提出了基于扩展状态观察者（ESO）的干扰补偿（DC）机制来估计和补偿PMSM系统速度环的总干扰。模拟和实验结果都验证了拟议的控制策略的有效性。
In this paper, an improved multi-step finite control set model predictive current control (FCS-MPCC) strategy with speed loop disturbance compensation is proposed for permanent magnet synchronous machine (PMSM) drives system. A multi-step prediction mechanism is beneficial to significantly improve the steady-state performance of the motor system. While the conventional multi-step prediction has the defect of heavy computational burden, an improved multi-step finite control set model predictive current control (IM MPCC) strategy is proposed by developing a new multi-step prediction mechanism. Furthermore, in order to improve the dynamic response of the system, a disturbance compensation (DC) mechanism based on an extended state observer (ESO) is proposed to estimate and compensate the total disturbance in the speed loop of the PMSM system. Both simulation and experimental results validate the effectiveness of the proposed control strategy.
