Model Predictive Torque Control System of Permanent Magnet Synchronous Motor Based on Active Disturbance Rejection Control

针对三相永磁同步电机(PMSM)系统,提出了基于自抗扰技术的模型预测转矩控制(MPTC)策略。采用矩阵变换器驱动PMSM的系统结构,以提高电机系统输入侧功率因数(PF);用MPTC选择最优电压空间矢量使系统有良好的转矩、磁链控制效果;ADRC速度调节器代替PI速度调节器能够使MC驱动的PMSM系统稳定运行,具有较好的转速和转矩控制效果,该策略具有更强的抗负载干扰能力和跟踪给定转速变化的能力。最后,通过Simulink仿真平台检验该策略的正确性和有效性。

For the three phase permanent magnet synchronous motor(PMSM)system,a model predictive torque control(MPTC)strategy based on active disturbance rejection technology is proposed.The matrix converter is used to drive the PMSM system structure to improve the input power factor(PF)of the motor system.MPTC is used to select the optimal voltage space vector so that the system has good torque and flux control effect.The ADRC speed regulator can replace the PI speed regulator to make the MC-driven PMSM system run stably,with better speed and torque control effect.The strategy has stronger ability to resist load interference and track the change of given speed.Finally,the correctness and effectiveness of the strategy are verified by Simulink simulation platform.
