Improved Model Predictive Control Method Based on Grid-connected Inverter
摘要
Abstract
Three-phase grid-connected inverters have been popularized owing to their high efficiency, higher power and low cost. The model predictive control method, which has the merits of high robustness and fast dynamic response, has been widely applied to the control of grid-connected inverters. However, the traditional predictive control has the disadvantage of irregular switching operation, which will reduce the current tracking accuracy and generate output pulse as well as electromagnetic noises.To solve the above problems,an improved model predictive control method is proposed based on the selection of switching states and the effective time of vectors. The second factor is considered as a dimension in the control, which improves the current tracking accuracy and reduces the inverter's output current distortion and electromagnetic noises. The feasibility and effectiveness of the proposed method were verified by simulation and experimental results.关键词
