Power Maximization of A Point Absorber Wave Energy Converter Using Improved Model Predictive Control

摘要

This paper considers controlling and maximizing the absorbed power of wave energy converters for irregular waves.With respect to physical constraints of the system, a model predictive control is applied. Irregular waves' behavior is predicted by Kalman filter method. Owing to the great influence of controller parameters on the absorbed power,these parameters are optimized by imperialist competitive algorithm. The results illustrate the method's efficiency in maximizing the extracted power in the presence of unknown excitation force which should be predicted by Kalman filter.
