Phase Control for the Oscillating Water Column

  • Conference paper
Hydrodynamics of Ocean Wave-Energy Utilization

Summary

In this paper we investigate the use of optimal control techniques for improving the efficiency of the power-conversion system in an oscillating water column device. A mathematical model of the system is developed and an optimal control strategy for power-generation is determined. An algorithm is described for solving the problem numerically given the incident wave form. The technique is applicable to irregular as well as regular waves. The results obtained show that the performance of the device can be significantly improved by means of a suitable control strategy.
