Emergency control of cyber-physical systems in the technological environment

Abstract

The task how to increase the industrial object crucial infrastructure reliability and safety is being studied formed with cyber-physical systems. To solve this task they represent a cyber-physical production as a complicated dynamic systems with tide and continuous conveyor cycles, which behavior is under control in the state parameters space. The cyber-physical systems actions of the inner technological environment factors and cyber-physical production external factors must be analyzed to study single and systematic actions of chaos creating character in equipment, which add some components to the control error. The emergency control is a directed cyber-physical action to maintain the cyber-physical production dynamic system in a non-variant state to the equipment failures and interferences. The control method and parameters are determined as a result of the assessment of the state of cyber-physical production performed in its phase space according to the predicted trajectories, probably indicating the dynamics of the technological environment and the risks of uncontrolled situations. The actual information of the cyber-physical production states includes the cyber-physical systems functionality modes data, which is proposed to be accumulated in a virtual environment to which the technological automatics of different hierarchy levels is connected to. The parametric states space dynamic system behavior trajectory forming principle is defined to make concrete separate cyber-physical systems and the cyber-physical production in general.
