Optimal controller design and constraints analysis of a sea wave energy converter

摘要

This paper studies the optimal control of a sea wave energy converter (WEC). A linear optimal controller is designed for the WEC to maximise the energy output. Rather than regulating states and control inputs as a conventional optimal controller normally does, the proposed optimal controller aims to maximise the energy output. The maximum output admissible set method is employed to estimate the feasibility of the proposed linear optimal controller when the input and state constraints need to be considered for safe operation of the WEC.
