Self-optimizing Control of an Air Source Heat Pump

2019 American Control Conference (ACC), 2019
Self-optimizing Control (SOC) is a method for finding appropriate controlled variables for which implementation of feedback control yields nearly-optimal operation regardless of variation in disturbances. The Jacobian estimation process in conventional SOC rely on an offline analysis of large amounts of steady-state data, which can be difficult in ...
