In this paper, the H2 guaranteed cost control problem of uncertain continuous T-S fuzzy systems is investigated. We approach this problem by considering the multiple Lyapunov function and utilizing the non-PDC controller. Sufficient conditions for ensuring certain H2 cost as well as asymptotical stability are derived and expressed in terms of LMIs. Unlike existing approaches, the assumption of known...
In this paper, a robust stability criterion is proposed for NCSs liable to model uncertainties and time-varying delays. The analysis concerns the establishment of a maximum allowable delay bound for continous time NCSs under parameter uncertainties. The new proposed criterion is based on the solution of a set of linear matrix inequalities (LMIs). Numerical examples are given to validate the theoretical...
The influence of neglected dynamics appearing as multiplicative uncertainties on a closed-loop system with input and output saturations is studied. Constructive conditions based on (possibly linear) matrix inequalities, are provided in order to compute the influence of these beforehand neglected dynamics on both the estimate of the closed-loop system basin of attraction and the performance. The case...
