A Pseudo-measurement Approach to State Estimation for Liquid Level Control of Separator in an OTEC Plant Using Uehara Cycle

Abstract

This research proposes a pseudo-measurement approach to construct a Kalman filter for a liquid level control system model of a separator in an Ocean Thermal Energy Conversion (OTEC) experimental plant with Uehara cycle. Pseudo-measurement is recognized as an estimation method for a system dynamics including unknown parameters. After constructing the system involving pseudo-measurement, the Kalman filter and the feedback controller are derived. The behavior of the system is evaluated through numerical simulation.
