Advanced Control of PMSG-based Wind Energy Conversion System Using Model Predictive and Sliding Mode Control

This paper proposes a sliding mode control (SMC) and a model predictive control (MPC) for controlling a PMSG wind turbine. The MPC forces the system to follow the defined sliding surface. The major advantages of SMC are robustness, fast response, and simple implementation, but one of the inconveniences is chattering. Therefore, the MPC has been proposed in this paper which uses the mathematical model of the system to predict the possible future behaviour of the controlled variables, and this technique allows the selection of the optimal voltage vector that leads to minimum error using a cost function which leads to low maintenance costs and low total harmonic distortion in current.
