Abstract: This paper develops a new fuzzy dynamic output-feedback controller for TS fuzzy systems with probabilistic actuator faults and time-varying input delay. The central sight is to consider the bounded H_∞ performance by the influence of stochastic faults, which are modelled by introducing Bernoulli distributed sequences. The novel stability criterion is established to guarantee the stochastic stabilisation of the resultant closed-loop system and satisfies a prescribed performance by implementing Lyapunov-Krasovskii's functional approach. Furthermore, the gain values of the controller are calculated by solving a set of linear matrix inequalities (LMIs). Eventually, an analytical example is provided to demonstrate the merits and applicability of the prospective method.
