The discrete-time hidden Markov model is employed to model the probabilistic relation between the network states and the controller-to-actuator (C-A) delays in networked control systems (NCSs). The NCS is modeled as a Markovian jump linear system and the C-A delay in the current sampling period is predicted. By taking the prediction into account, a state-feedback controller is designed to compensate for the stochastic C-A delays. The superiority of the proposed method is demonstrated by the comparative simulation experiments.
