This paper presents a model predictive current controller and its application to the inner current control loop of a field oriented controller. In a stationary reference frame, the proposed control scheme keeps the α and β currents within given hysteresis bounds while minimizing the switching frequency of the inverter. Based on an internal model of the drive, the controller predicts the drive's future...
This paper presents a model predictive current controller and its application to ac electrical drives. In a stationary reference frame, the proposed control scheme keeps the α and β currents within given hysteresis bounds while minimizing the switching frequency of the inverter. Based on a internal model of the drive, the controller predicts the drive's future behavior for each switching sequence,...
This paper presents a comparative analysis of two Model Direct Predictive Controllers (MDPC), which are applied to the inner loop current control of a field-oriented control scheme for an ac drive. A model of the controlled system which includes the dynamics of the inverter (boolean and discrete) and also of the machine (continuous) is employed to predict the future stator currents for a pre-defined...
