This paper compares three methods for control of the superheat in a refrigeration system. A traditional gain scheduled PI-based controller, a predictive functional controller (PFC) and a predictive functional controller with a neural network model (P

In this work we formulate a control strategy for the control of a Wave Energy Converter (WEC) aiming to maximize power take off taking into account losses in the conversion from mechanical to electrical power. The analysis is based on a point absorbe

This paper describes adaptive control of the superheat in a refrigeration system. Traditionally, the superheat is PI controlled using constant gain and integration time, which often will have a conservative tuning. On-line update of the controller pa
