Abstract
This paper focuses on a refrigeration system based on vapour compression. The opening of an expansion valve and the speed of a compressor are the manipulated inputs to control the refrigeration temperature and the overheating in order to fulfil the refrigeration needs as well as to pay attention to the system efficiency. Decentralised controllers plus a decoupler in one direction prove to be a simple control solution to achieve the objectives. Nonlinearities and couplings are modelled as uncertain parameters of plant transfer functions, and then, robust controllers are designed under QFT paradigm.
