A new strategy framed in the field of model predictive direct current control applied to surface permanent magnet synchronous generator (SPMSG) is presented. Compared to conventional space vector control systems, the proposed predictive strategy reduces the number of PI regulators and maintains the advantages of a fixed switching frequency. It also performs a faster response providing a smooth electromagnetic torque and smooth active and reactive power control. The dynamic performance of the proposed control is first analyzed by means of simulations in MATLAB Simulink environment and then compared with two other model predictive controls. Also, the performance of the control is analyzed in simulation using a simple model of an oscillating water column power plant. This application was chosen because it is a difficult case study that demands a fast torque control to handle the power take-off system. Later, the proposed method is tested in a customized SPMSG-based laboratory setup. This article is accompanied by a video.
