摘　　要：为了提高五相永磁同步电机控制系统的性能,本文提出了适用于五相永磁同步电机谐波子空间的目标函数构造方法。采用有限集模型预测转矩控制策略,并基于分数阶滑模变结构理论提出了不确定非线性的分数阶速度控制器。仿真结果表明:该控制方法具有减小电机转矩、磁链脉动的效果,同时也提高了空子系统跟随精度;减小了速度超调和响应时间,提高系统稳定性。采用基于分数阶滑模控制的五相永磁同步电机的有限集模型预测转矩控制优化策略具有较强的负载鲁棒性,有良好的动态性能和静态性能,优化的控制系统提高了电机的输出性能和可靠性。In order to improve the performance of the five-phase permanent magnet synchronous motor(FP-PMSM)control system,an objective function construction method suitable for harmonic subspace of FP-PMSM is proposed in this paper.It adopts a finite-set-model predictive torque control(FCS-MPTC)strategy and a fractional speed controller(FOSMC)with uncertain nonlinearity based on the fractional-order sliding model.The simulation results show that reducing torque and flux pulsation and system following error makes the system have higher accuracy.It reduces speed overshoot and response time,improving system stability.The FCS-MPTC optimization strategy based on FP-PMSM of FOSMC has strong load robustness,good dynamic and static performance,and the optimized control system improves the output performance and reliability of the motor.
