Multirate Periodic Systems, o-Gap Metric and Robust Stabilization
نویسندگان
چکیده
A new discription of multirate systems, called multirate periodic system, is given using the concept of periodic time-varying input-output spaces. We then de ̄ne the o -gap metric of two multirate periodic systems and study the robust stabilization with this metric. The optimal robust stabilization margin is explicitly computed and an obsever-form suboptimal controller is given. The solution amounts to solving two discrete-time algebraic Riccati equations and an extended Parrot problem.

Definition of General Operator Space and The s-gap Metric for Measuring Robust Stability of Control Systems with Nonlinear Dynamics
In the recent decades, metrics have been introduced as mathematical tools to determine the robust stability of the closed loop control systems. However, the metrics drawback is their limited applications in the closed loop control systems with nonlinear dynamics. As a solution in the literature, applying the metric theories to the linearized models is suggested. In this paper, we show that usin...

A relation between coprlme fractions and the gap metric is presented. USlng this result we provlde some sufficient condi Hons for BIBO robust stabll1za tion for a very wlde class of systems. These conditions allow the plant and compensator to be disturbed simutaneously. K.e.Y words: Robust stabllization; Gap metric; Coprime fraction.
متن کاملContinuity of optimal robustness and robust stabilization in slowly varying systems
Continuity properties of the optimal design of robust stabilization in the gap metric are investigated. In general the optimal design in the gap metric lacks continuity properties required for certain H” adaptation schemes for slowly varying systems. On the other hand, the S-suboptimal central design is shown to be Lipschitz continuous. Applications of the continuity properties and frozen-time ...
متن کاملDelay-dependent robust stabilization and $H_{infty}$ control for uncertain stochastic T-S fuzzy systems with multiple time delays
In this paper, the problems of robust stabilization and$H_{infty}$ control for uncertain stochastic systems withmultiple time delays represented by the Takagi-Sugeno (T-S) fuzzymodel have been studied. By constructing a new Lyapunov-Krasovskiifunctional (LKF) and using the bounding techniques, sufficientconditions for the delay-dependent robust stabilization and $H_{infty}$ control scheme are p...
متن کاملRobust stabilization of a class of three-dimensional uncertain fractional-order non-autonomous systems
This paper concerns the problem of robust stabilization of uncertain fractional-order non-autonomous systems. In this regard, a single input active control approach is proposed for control and stabilization of three-dimensional uncertain fractional-order systems. The robust controller is designed on the basis of fractional Lyapunov stability theory. Furthermore, the effects of model uncertai...
