A framework for robustness analysis of input constrained nite receding horizon control is presented. Under the assumption of quadratic upper bounds on the nite horizon costs, we derive suucient conditions for robust stability of the standard discrete-time linear-quadratic receding horizon control formulation. This is achieved by recasting conditions for nominal and robust stability as an implic...

This paper is concerned with the design of gain-scheduled controllers for Linear Parameter-Varying systems. Two alternative LMI characterizations are investigated. Both characterizations are amenable to a nite number of LMI conditions either via a gridding of the parameter range or via grid-free techniques which rely on multi-convexity concepts. Practicality and implementation issues are discus...

In this paper, we consider the guaranteed cost filtering design method for time-varying delay systems with parameter uncertainties by LMI(Linear Matrix Inequality) approach. The objective is to design a stable guaranteed cost filter which minimizes the guaranteed cost of the closed loop system in filtering error dynamics. The sufficient conditions for the existence of filter, the guaranteed cos...

This paper addresses the problem of robust stability for two-dimensional systems with delays in the state. To solve this problem, the Lyapunov second method is used. The resulting condition is written in terms of linear matrix inequalities and it is dependent on the size of delays. This fact allows us to reduce the conservatism in the stability analysis of twodimensional systems with state dela...

Weiche strukturvariable Regler mit impliziten Ljapunov-Funktionen sind nichtlineare Zustandsrückführungen für lineare Systeme mit Stellgrößenbeschränkung. Die Parameter des Reglers werden kontinuierlich abhängig vom Systemzustand verändert, sodass der Stellgrößenbereich möglichst gut ausgenutzt wird, ohne die Beschränkung zu verletzen. Dadurch kann ein fast zeitoptimales Verhalten bei einem ver...

This paper studies fuzzy filtering design for state estimation of nonlinear discrete-time systems with bounded but unknown disturbances. First, the Takagi and Sugeno fuzzy model is proposed to represent a nonlinear system. Next, using a linear matrix inequality (LMI) approach, the fuzzy filtering problems are characterized in terms of a linear matrix inequality problem (LMIP). The LMIP can be e...

This paper is concerned with the problem of robust static output feedback guaranteed cost control for a class of nonlinear discrete systems with mixed time-varying delays. The proposed controller uses the output measurement to robustly exponentially stabilize the closed-loop system and guarantee an adequate level of system performance. By constructing a set of improved Lyapunov-Krasovskii funct...

Design of an observer based controller for a class of fractional order systems has been done. Fractional order mathematics is used to express the system and the proposed observer. Fractional order Lyapunov theorem is used to derive the closed-loop asymptotic stability. The gains of the observer and observer based controller are derived systematically using the linear matrix inequality approach....

A memoryless state feedback control law is developed such that the closed-loop system containing point and distributed time-delays is asymptotically stable and the H∞-norm of the transfer function from the disturbance to the controlled output is reduced to some predefined level. The feedback is obtained by solving a parameter-dependent linear matrix inequality. When the state variables are not ...
