To reduce conservatism, we adopted two approaches, pre-computing and/or free-weighting matrices, to manipulate the Lyapunov functional candidates, where we incorporate the more terms, and used them to analyse the robust control problem for uncertain stochastic systems with time-delay successfully. Then, we gave numerical examples to demonstrate the effectiveness of the two approaches.
In this study, the engine speed control algorithm is developed. The system augmented method based on the local linearized dynamic internal combustion engine model is presented for design of feedback controller without steady-state error. For multi-operating points local linearization of engine model the Takagi-Sugeno (T-S) fuzzy models with time-delay are presented, and the stability conditions are...
The problems of robust stability and L2-gain analysis and synthesis for a class of uncertain discrete-time switched systems with time-delay are addressed. Based on the constructive use of an appropriate switched Lyapunov function, switched systems with convex-bounded parameter uncertainties in all system matrices are investigated to make the linear switched systems are uniform quadratic stability...
The design of robust Hinfin controller for a class of uncertain neutral systems with varying state delay and input control delay is considered. The uncertainties are norm-bounded and the states of the uncertain neutral systems are available. Combining the linear matrix inequality with Lyapunov functions by proper assumption, the existent conditions of quadratic stabilization and Hinfin state feedback...
This paper is devoted to robust stability analysis of linear continuous-time systems with time-delay that are composed of polytopic uncertain subsystems. A new delay-dependent analyzing approach is proposed to reduce the conservativeness in stability analysis for such systems. The stability condition of delay-dependent given in terms of bilinear matrix inequalities (BMI) is developed for the systems...
The notions of the practical stability in probability and in the pth mean, and the practical controllability in probability and in the pth mean, are introduced for some stochastic systems with Markovian jump parameters and time-varying delays. Sufficient conditions on such practical properties are obtained by using the comparison principle and the Lyapunov function methods. Besides, for a class of...
Based on the robust invariant set, Hinfin controller designing problem for uncertain discrete time-delay system with disturbance and input constraint is considered in this paper. At first, a state feedback controller was designed, when the disturbance belongs to a convex polytope, a control invariant set was derived based on the revised Lyapunov Krasovskii function, and inside this control invariant...
