Abstract

In this paper an adaptive supervisory controller is designed to control the superheat temperature of a supermarket refrigeration system. The adaptive controller utilizes a switching algorithm with a forgetting factor. At each time step, the switching algorithm selects the best model among multi models using a supervisory monitoring signal. Each model corresponds to a controller; hence the corresponding controller to the selected model generates the required signal to determine the opening degree of an expansion valve. Simulations results of the proposed controller on a model of superheat of a supermarket refrigeration system for different operating point, show very satisfactory performance.
