Variable Capacity Control of Compressor for Automotive Air-Conditioning System using Reference Model Following Based Sliding Mode Control

Abstract

This paper proposes a new control technique for compressor of Automotive Air-Conditioning System (AACS). It is based on Reference Model Following Based Sliding Mode Controller (RMFSMC) with disturbance observer. Variable Capacity Control (VCC) is widely attracted from saving energy and keeping the car comfortable. But it is difficult to realize it, since it has complex and nonlinear characteristics. To fix the problem, the mathematical model is derived from System Identification (System ID) and the RMFSMC has been designed. This paper introduces the developing process, simulations, and its experimental results.
