Analysis of Real-Time Control Systems with Time Delays

We discuss modeling and analysis of real-time control systems subject to random time delays in the communication network. A new method for analysis of given control schemes is presented. The state of the network is modeled by a Markov chain and Lyapunov equations for the expected LQG performance are presented. An example that illustrates the results is given.
