Model prediction flux linkage control method and system based on alpha-beta axis

The invention discloses a model prediction flux linkage control method and system based on an alpha-beta axis, and the method employs a torque PI controller to replace a torque angle calculation part in a conventional method, reduces the calculation burden, avoids the calculation error problem caused by the misalignment of parameters in a calculation formula, and improves the calculation precision. Sector judgment and flux linkage amplitude judgment are used for replacing flux linkage prediction and value function optimizing processes in a traditional method, the algorithm operation time is effectively shortened, and compared with the traditional method, the control process is simpler; in addition, the control process does not need rotation coordinate transformation, motor parameters are not included, and the control robustness is effectively improved. 本发明公开了一种基于α-β轴的模型预测磁链控制方法及系统，本发明使用转矩PI控制器替代传统方法中转矩角计算部分，减轻了计算负担，避免了因计算公式里参数失准而带来的计算误差问题，利用扇区判断和磁链幅值判断代替传统方法中磁链预测和价值函数寻优过程，有效减少了算法运算时间，相较于传统的方法，控制过程更加简单；并且本发明的控
