Improving Closed-Loop Stability of Second-Order LTI Systems by Hybrid Static Output Feedback

چکیده
In this paper, we consider the problem of improving stability property for a class of second-order LTI systems by hybrid static output feedback. The improvement is measured in term of the stability index defined in the paper, and the systems under consideration are stabilizable with certain stability index by a single static output feedback. We show that an arbitrary desired stability index can be achieved for the system by designing a hybrid controller composed of two static output feedbacks and a conic switching law. An example is given to demonstrate the applicability of the result.

Adaptive fuzzy pole placement for stabilization of non-linear systems
A new approach for pole placement of nonlinear systems using state feedback and fuzzy system is proposed. We use a new online fuzzy training method to identify and to obtain a fuzzy model for the unknown nonlinear system using only the system input and output. Then, we linearized this identified model at each sampling time to have an approximate linear time varying system. In order to stabilize...
متن کاملEigenvalue Assignment Of Discrete-Time Linear Systems With State And Input Time-Delays
Time-delays are important components of many dynamical systems that describe coupling or interconnection between dynamics, propagation or transport phenomena, and heredity and competition in population dynamics. The stabilization with time delay in observation or control represents difficult mathematical challenges in the control of distributed parameter systems. It is well-known that the stabi...
متن کاملEvent-Triggered Decentralized Dynamic Output Feedback Control for LTI Systems ?
In this paper we investigate event-triggered controllers for dynamic output feedback control of Linear Time Invariant (LTI) systems. We propose a systematic methodology for designing implicitly verified event-triggered dynamic output feedback controllers for LTI systems that are observable and controllable. Event-triggering conditions for sampled-data implementation of the observer and the cont...
متن کاملSingular Perturbation Theory in Output Feedback Control of Pure-Feedback Systems
This paper studies output feedback control of pure-feedback systems with immeasurable states and completely non-affine property. Since availability of all the states is usually impossible in the actual process, we assume that just the system output is measurable and the system states are not available. First, to estimate the immeasurable states a state observer is designed. Relatively fewer res...
متن کاملLocalization of Eigenvalues in Small Specified Regions of Complex Plane by State Feedback Matrix
This paper is concerned with the problem of designing discrete-time control systems with closed-loop eigenvalues in a prescribed region of stability. First, we obtain a state feedback matrix which assigns all the eigenvalues to zero, and then by elementary similarity operations we find a state feedback which assigns the eigenvalues inside a circle with center and radius. This new algorithm ca...
