A continuous control approach to point absorber wave energy conversion

Abstract

In recent years the control of Wave Energy Conversion (WEC) systems has been a challenging research topic. A 1/50th scale buoy system has been constructed at the University of Hull for modelling, verification and control. This study focuses on the time-varying state space model development of this direct-drive WEC with a tubular permanent magnet linear generator (TPMLG). A new form of control is developed, with (i) an adaptive impedance tuning system based on a mechanical-electrical analogue, and (ii) position and current tracking for power maximisation, physical constraint realisation and generator dynamic linearisation. Simulation results of regular and irregular waves indicate this control strategy can achieve an acceptable energy conversion efficiency.
