Decentralized H∞ Control and Reliability Analysis for Symmetric Composite Systems: Dynamic Output Feedback Case
نویسندگان
چکیده
The dynamic output feedback decentralized H∞ control and the reliability of the designed system (the maximal number of control-channel outages when the performance is still acceptable) is studied for symmetric composite systems. It is shown that the decentralized H∞ control problem can be simplified to a simultaneous H∞ control problem for two modified subsystems. A design method based on the simultaneous H∞ control method is given. Simple methods for testing the reliablity are presented using the special structure of symmetric composite systems.

Reliable linear-quadratic control for symmetric composite systems
In recent years there has been great interest in the study of symmetric composite systems. Symmetric composite systems are systems composed of identical subsystems which are symmetrically interconnected. The motivation for studying this class of systems is due to its very diverse application areas, such as in electric power systems, industrial manipulators and computer networks (Lunze 1986, Sun...
متن کاملDecentralized H_infty Quantizers Design for Networked Complex Composite Systems
The objective of the paper is to propose an approach to decentralized networked quantized state feedback H∞ controller design for a class of complex symmetric composite continuous-time systems. The effect of data-packet dropouts and communication delays between the plant and the local controller as well as quantizers design are included in the design of asymptotically stabilizing controller and...
متن کاملPassivity-Based Stability Analysis and Robust Practical Stabilization of Nonlinear Affine Systems with Non-vanishing Perturbations
This paper presents some analyses about the robust practical stability of a class of nonlinear affine systems in the presence of non-vanishing perturbations based on the passivity concept. The given analyses confirm the robust passivity property of the perturbed nonlinear systems in a certain region. Moreover, robust control laws are designed to guarantee the practical stability of the perturbe...
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 کاملDecentralized Hybrid Feedback Stabilization for a Class of Switched Composite Systems
In this paper, a new class of composite systems, called switched composite systems, whose subsystems are switched systems is proposed. This class of systems can be viewed as a natural extension of both composite systems and switched systems. We design decentralized switching laws for this class of systems to be asymptotically stable. For general composite systems, decentralized hybrid state fee...
