Abstract
In this paper the individual zone temperature control of a multizone building is considered. The investigations are based upon a study of Davison and Solomon (1983) in which a partially decentralized control scheme is applied and investigated using for the control of a particular zone temperature as measurements besides this temperature itself only those from immediate neighbouring zones. A more complete model of the house is used here however that allows more coupling between the zones and that takes the input constraints into account. It is shown that the special structure of Davison’s controller and its properties applies to more general cases and that the identification of its parameters can be simplified. A second closed loop control strategy is used with completely decentralized PI-controllers. Open loop and closed loop simulations for the two control strategies show for different house types the performances under setpoint changes.
