摘要

The supermarket refrigeration system typically has a distributed control structure, which neglects interactions between its subsystems. These interactions from time to time lead to a synchronization operation of the display cases which causes excessive wear on the compressors and increased energy consumption. The paper analyzes the synchronization behaviour based on a piecewise-affine switched model and proposes a new de-synchronization scheme by chaotifying the system using delayed feedback control. Both theoretical analysis and numerical simulation shows the effectiveness of the scheme.
