摘　　要：针对传统有限状态控制集模型预测(FCS-MPC)控制方法计算量大的问题,提出了一种优化的模型预测(OMPC)控制方法。利用无差拍思想,将参考输出电流转化为期望输出电压,然后根据期望输出电压矢量在两相静止坐标系的位置,提出了一种逆变级开关状态的选择方法,整流级只需要3次寻优计算,逆变级不存在开关状态的遍历寻优。相对于传统FCS-MPC,优化模型预测将系统寻优次数由24次减少到3次,很大程度上降低了系统计算量。最后通过Matlab/Simulink仿真和TMS320F28335控制器验证了该方案的有效性。Aiming at large amount of calculation in the conventional finite-control-set model-predictive control(FCS-MPC),an optimized model predictive contro(l OMPC)control method was proposed.The reference output current was converted to the desired output voltage with deadbeat,and then according to the position of the expected output voltage vector in the two-phase static coordinate system,a switching state selection method for the inverter stage was proposed,the rectifier stage with evaluation needs noly 3 switching states,there was no ergodic optimization for switching states in the inverter stage.Compared with traditional FCS-MPC,the number of optimization calculations was reduced from 24 to 3,the amount of calculation of the control system was reduced to a great extent.Finally,the effectiveness of the proposed algorithm was verified by the simulation model of indirect matrix converter and TMS320F28335.
