Liquid Level Control of Separator in an OTEC Plant with Uehara Cycle

抄録

In this paper, the liquid level control of separator in an ocean thermal energy conversion (OTEC) experimental plant with Uehara cycle is considered. A liquid level model of separator is constructed based on not only experimental data about the characteristics between the liquid level and the valve opening but also simulations using a stochastic model. The control system for the liquid level control of separator is designed by employing the LQG control theory. The usefulness of both the liquid level model and the control system is confirmed through simulations.
