Model Predictive Control of Multilevel Cascaded H-Bridge Inverters
IEEE Transactions on Industrial Electronics, 2010 This paper presents a model predictive current control algorithm that is suitable for multilevel converters and its application to a three-phase cascaded H-bridge inverter. This control method uses a discrete-time model of the system to predict the future value of the current for all voltage vectors, and selects the vector which minimizes a cost ...
