چکیده

Synchronisation arises in dynamical systems that are composed of a number of interconnected subsystems. In the paper synchronization in a particular application a supermarket refrigeration system is studied. The temperature control in supermarket display cases is typically maintained by a number of distributed hysteresis controllers. Synchronization is then manifested by the opening and closing actions of expansion valves at the same time. Synchronization is interpreted in this paper as a limit cycle in a state space created by transitions among piecewise-affine dynamical systems. Stability of the resultant limit cycle is examined by a Poincaré like map. We show that the synchronisation takes place if the corresponding Poincaré map is stable.

Stochastic Analysis of Synchronization in a Supermarket Refrigeration System

Display cases in supermarket systems often exhibit synchronization, in which the expansion valves in the display cases turn on and off at exactly the same time. The study of the influence of switching noise on synchronization in supermarket refrigeration systems is the subject matter of this work. For this purpose, we model it as a hybrid system, for which synchronization corresponds to a perio...

Hybrid NMPC of a Supermarket Refrigeration System Using Sequential Optimization

Supermarket refrigeration systems are hybrid systems due to switching of the continuous dynamics and due to the presence of discretely switched actuators such as valves and compressors. The main control goal for these systems is to keep temperature and pressure levels within tight bounds while minimizing the wear of the compressors. In our previous work, a hierarchical model-predictive control ...

Finite Time Mix Synchronization of Delay Fractional-Order Chaotic Systems

Chaos synchronization of coupled fractional order differential equation is receiving increasing attention because of its potential applications in secure communications and control processing. The aim of this paper is synchronization between two identical or different delay fractional-order chaotic systems in finite time. At first, the predictor-corrector method is used to obtain the solutions ...

Modified Sliding-Mode Control Method for Synchronization a Class of Chaotic Fractional-Order Systems with Application in Encryption

In this study, we propose a secure communication scheme based on the synchronization of two identical fractional-order chaotic systems. The fractional-order derivative is in Caputo sense, and for synchronization, we use a robust sliding-mode control scheme. The designed sliding surface is taken simply due to using special technic for fractional-order systems. Also, unlike most manuscripts, the ...
