WebJan 16, 2024 · MPC can be divided into two major classes, finite control set (FCS) MPC which directly optimizes the switching state and continuous control set (CCS) MPC which optimizes a duty cycle that is given to a modulator which then creates the switching state of the system. Therefore, FCS-MPC is proposed in this paper for DVR applications. WebJul 18, 2024 · Equipped with a modulator, CCS-MPC produces a constant switching frequency and has a lower current ripple than FCS-MPC.
