基于混合逻辑动态模型的三相逆变电路有限控制集模型预测控制策略
FCS-MPC Strategy for Inverters Based on MLD Model
摘要
Abstract
Since the conventional switch function model of inverters can only describe the controlled transition, while ignore the conditional transition of inverters, this study builds a mixed logical dynamical (MLD) model for inverters and treats it as a predictive model to work out a finite control set model predictive control (FCS-MPC) strategy for inverters. The FCS-MPC strategy takes full account of the discreteness of inverters, and selects the switch state that minimizes the objective function as the control signal for inverters to control the output voltage, which simplifies the optimization of MPC without any modulators. In addition, a load current observer is designed based on the full state observer, which enhances the robust of the controller. The simulation and test results validate the proposed method.关键词
