- Abstract
The H ∞ control problem is studied for discrete-time Markov jump systems with both discrete and distributed delays. The controller to be designed allows for mode mismatch with the plant, and the mode mismatch behavior is described by a hidden Markov model. The conditional probabilities are permitted to be uncertain, which belong to an interval with precise upper and lower bounds. A sufficient condition that ensures the stochastic stability and H ∞ disturbance-attenuation performance of the system is derived by employing a Lyapunov functional involving multiple quadratic items associated with the system modes. Then, two design methods are proposed for the desired controller. The first method does not utilize the property that the row sum of the conditional probability matrix is one, while the second method incorporates this property into the design process. The scenario where all the conditional probabilities are known in advance is also investigated, and corresponding controller design methods are presented. Finally, two examples are applied to validate the effectiveness of the design methods.
