The paper presents the implementation of Finite Control Set Model Predictive Control (FCS-MPC) in power inverter loads. The proposed new technique makes the Multilevel Inverter (MLI) using series and parallel voltage sources. The switching states of the FCS-MPC are directly applied to the power inverter without any modulation stage. The results show that the outputs are more efficient and with very less harmonics. The simulation has been analyzed using MATLAB/Simulink and a hardware prototype is implemented. It is concluded that MPC offers a new and very attractive alternative for controller in power inverters.

 
 

Model Predictive Control (MPC) has now approximately three decades of sustained development and is considered one of the most important advances in process control. In effect, MPC is used today in the process industry, especially in petrochemical plants. MPC offers many advantages; in particular, it can be used in a variety of processes, being simple to apply in multivariable systems. Furthermore, the inclusion of nonlinearities and constraints in the control law is straightforward (Lee, 2011). In the last decade, the use of MPC has been reported in fields ranging from vehicle traction and suspension control to automotive power trains and thermal management. Control platforms such as Digital Signal Processors (DSPs) or Field Programmable Gate Arrays (FPGAs) have been widely used in power electronics (Jose et al., 2013). The Multilevel Inverter (MLI) in MPC plays an important role in sliding mode controller as illustrated by Barros and Silva (2007). The computational power of these hardware devices has experienced a sustained increase in the last few decades. This high computational power has made possible the implementation of new and generally more complex control techniques, e.g., fuzzy, adaptive, sliding mode and predictive control. In particular, MPC has demonstrated to offer a very simple and an effective alternative to classical control (Geyer et al., 2009).
