| Abstract: | Aiming at the nonlinear discrete system featuring infinite distributed delay and T-S fuzzy model, a new actuator fault model with interval-probabilistic distribution is proposed by analysing actuator fault features. By applying Lyapunov stability theory and linear matrix inequality (LMI) technology, the sufficient condition is given for the existence of fault tolerant control (FTC) based on fault-distribution and delay dependence with mean square stableness. An illustrative example is exploited to show the effectiveness of the proposed design procedures. |
