Description
Summary:This paper presents a resonant finite control set model predictive control (RFCS-MPC) of a single-phase boost rectifier with an embedded resonant mode in the stationary frame. The current control system is realised in a cascade structure where the inner-loop control problem is formulated using the conventional unit prediction horizon FCS-MPC. Then the boost rectifier and its FCS-MPC loop are modelled as a unit delay. The resonant mode in then introduced using a digital resonant shift operator. Following the current control design, a proportional integral (PI) controller is designed in the outermost loop for the DC-link voltage control. It is shown through several simulation results that, unlike the conventional FCS-MPC, the proposed RFCS-MPC approach maintains zero steady-state error with reasonable robustness in the presence of disturbances and parameter mismatches in the current control loop.
