基于模块统一脉宽调制的模块化多电平变换器优化模型预测控制
Submodule Unified Pulse Width Modulated Based Optimized Model Predictive Control for Modular Multilevel Converters
摘要
Abstract
Aiming at reducing the computational time and the number of weight factors,this paper proposed an optimized model predictive control.By controlling the driving signal of the corresponding IGBTs,this method can make phase current follow the given value at a fast speed and inhibit the circulating current.Also it can achieve a stable submodule capacitor voltage by using a submodule capacitor voltage sorting method.Compared with thetraditional model predictive control,this method doesn't need the cost function,and can reduce computation time.In addition,it can effectively control the phase current,circulating current and submodule capacitor voltage.It can be widely used in the occasion of high requirements.Finally the effectiveness of the proposed algorithm is verified by the simulation model of the modular multilevel converter and the experimental prototype.关键词
