| 永磁同步发电机系统常用控制策略是电压外环和电流内环的双闭环矢量控制，在实际PI控制中，控制效果对系统参数的依赖度较高，且不同工况下最优PI参数不同，因此在变工况控制情况下控制效果不佳。课题组针对永磁同步发电机的最大转矩电流比（MTPA）控制，提出了一种基于多目标有限集模型预测控制(FCS MPC)的MTPA控制方法，在FCS MPC基础上，通过多目标优化建立代价函数，实现转矩参考值跟踪、MTPA优化控制和最大电流约束，可以代替传统的基于双闭环的矢量控制及电流模型预测控制，具有较强的鲁棒性和良好的动静态性能。通过MATLAB/Simulink仿真分析及基于STM32F407IGT6的硬件系统的实验对比，验证了方法的可行性，有效实现了永磁同步发电机的MTPA控制。 |

| For the permanent magnet synchronous generators, the commonly used control strategy was the double closed loop vector control which contains voltage outer loop and current inner loop. However, in PI control, the control effect was dependent on system parameters. Optimal PI parameters were different under different working conditions, so the control effect could be not good under when the working condition changed. Aiming at the maximum torque per ampere (MTPA) control of permanent magnet synchronous generators, a MTPA control method based on multi objective finite control set model predictive control (FCS MPC) was proposed. On the basis of FCS MPC, through multi objective optimization, the cost function was established to realize torque reference value tracking, MTPA control and maximum current constraint, which can replace the traditional vector control based on double closed loop vector control and the current model predictive control. It had strong robustness and nice dynamic and static performance. Through MATLAB/Simulink simulation analysis and experimental comparison based on the STM32F407IGT6 hardware system, the feasibility of the method is verified, and the MTPA control of the permanent magnet synchronous generator is effectively realized. |
