Abstract :
Integrated control system design, which requires interactions between the disciplines of communication systems and control systems, is introduced. An integrated control system has disparate and spatially distributed subsystems interconnected via a common communication channel. Digital data from sensor to controller and from controller to actuator are multiplexed along with traffic from other control loops and management functions. The asynchronous time-division multiplexing introduces time-varying and possibly stochastic delays in the control loops, degrading system dynamic performance. The analysis of delayed control systems is treated, covering the stochastic Lyapunov method approach, the D-partition method, and the method of steps.<>
