State Feedback Stabilization with Guaranteed Transient Bounds
نویسندگان
چکیده
We analyze under which conditions linear time-invariant state space systems can be stabilized by static linear state feedback such that prescribed transient bounds hold pointwise in time for the trajectories of the closed loop system. We introduce the concepts of (M,β)-stability and quadratic (M,β)-stability which guarantee a transient bound M along with a decay rate β < 0. Necessary and sufficient conditions for quadratic (M,β)-stabilizability are derived which can be expressed in terms of linear matrix inequalities. A full characterization of general (M,β)-stabilizability is still missing. However, we obtain necessary and sufficient criteria under which a given system can be transformed by linear state feedback into a closed loop system generating a strict contraction semigroup with respect to the spectral norm.

A new switching strategy for exponential stabilization of uncertain discrete-time switched linear systems in guaranteed cost control problem
Uncertain switched linear systems are known as an important class of control systems. Performance of these systems is affected by uncertainties and its stabilization is a main concern of recent studies. Existing work on stabilization of these systems only provides asymptotical stabilization via designing switching strategy and state-feedback controller. In this paper, a new switching strate...
متن کاملStabilization of Linear Systems with Prescribed Transient Bounds
The feedback synthesis of linear systems satisfying certain exponential bounds on their transient behavior is studied. We present sufficient conditions ensuring that there exists a state feedback matrix such that the closed loop system satisfies a desired exponential growth bound. Special interest is directed to the case of generating contraction semigroups, which under certain conditions can b...

متن کاملAdaptive Robust Control for a Class of Uncertain Time–delay Systems via Output Feedback
The problem of robust stabilization is considered for a class of systems with the delayed state perturbations, uncertainties, and external disturbances. It is assumed that the upper bounds of the delayed state perturbations, uncertainties, and external disturbances, are unknown. An improved adaptation law with σ– modification is first introduced to estimate these unknown bounds. Then, by making...
