Abstract

A non-linear control method for an air conditioning system utilizes fuzzy logic to regulate the activation of a displacement control valve for a variable displacement compressor for maintaining a system parameter, such as the evaporator outlet pressure or temperature, at a desired value. The control inputs include the system parameter to be controlled and a refrigerant pressure that reflects changes in the compressor displacement.
