The 24th Chinese Control and Decision Conference (第24届中国控制与决策学术年会 2012 CCDC)

This paper considers the distributed quadratic stabilization problems of uncertain continuous-time linear multiagent systems with undirected communication topologies. It is assumed that the agents have identical nominal dynamics while subject to different norm-bounded parameter uncertainties, leading to weakly heterogeneous multi-agent systems. A distributed controller is proposed, based on the relative states of neighboring agents and a subset of absolute states of the agents. It is shown that the distributed quadratic stabilization problem under such a controller is equivalent to the H∞ control problems of a set of decoupled linear systems having the same dimensions as a single agent. A two-step algorithm is presented to construct the distributed robust controller, which does not involve any conservatism and meanwhile decouples the feedback gain design from the communication topology. Furthermore, the distributed quadratic H∞ control problem of uncertain linear multi-agent systems with external disturbances is discussed, which can be reduced to the scaled H∞ control problems of a set of independent systems whose dimensions are equal to that of a single agent.

Robust fault-sensitive synchronization of a class of nonlinear systems

Chinese Physics B 2011年第2期20卷 148-157页

作者：徐式蕴杨莹刘仙汤涌孙华东 China Electric Power Research Institute State Key Lab for Turbulence and Complex Systems Department of Mechanics and Aerospace EngineeringCollege of EngineeringPeking University Department of Automation Yanshan University

Aiming at enhancing the quality as well as the reliability of synchronization, this paper is concerned with the fault detection issue within the synchronization process for a class of nonlinear systems in the existence of external disturbances. To handle such problems, the concept of robust fault-sensitive （RFS） synchronization is proposed, and a method of determining such a kind of syncbronization is developed. Under the framework of RFS synchronization, the master and the slave systems are robustly synchronized, and at the same time, sensitive to possible faults based on a mixed H_/H~ performance. The design of desired output feedback controller is realized by solving a linear matrix inequality, and the fault sensitivity H index can be optimized via a convex optimization algorithm. A master-slave configuration composed of identical Chua＇s circuits is adopted as a numerical example to demonstrate the effectiveness and applicability of the analytical results.

Distributed adaptive attitude synchronization of multiple spacecraft

Science China(Technological Sciences) 2011年第8期54卷 1992-1998页

作者： LI ZhongKui DUAN ZhiSheng School of Automation Beijing Institute of Technology Beijing 100081 China State Key Lab. for Turbulence and Complex Systems Department of Mechanics and Aerospace Engineering College of Engineering Peking University Beijing 100871 China

This paper addresses the distributed attitude synchronization problem of multiple spacecraft with unknown inertia matrices. Two distributed adaptive controllers are proposed for the cases with and without a virtual leader to which a time-varying reference attitude is assigned. The first controller achieves attitude synchronization for a group of spacecraft with a leaderless communication topology having a directed spanning tree. The second controller guarantees that all spacecraft track the reference attitude if the virtual leader has a directed path to all other spacecraft. Simulation examples are presented to illustrate the effectiveness of the results.

Abstract In this paper, we address the data-driven design of observers for the process monitoring and control purposes. Instead of identifying a standard state space model, our design schemes are based on the identification of the so-called parity subspace. Two design schemes are developed, which allow a direct design of (a) observer-based fault detection systems (b) a full order observer for the estimation of the process state variables. The achieved results are illustrated by a benchmark example.

Robust Global Stabilization of Linear systems via Bounded Control

Abstract In this paper, the robust stabilization of asymptotically null-controllable linear systems via bounded controls is revisited. Based on the notion of “converging-input bounded-state” stability rather than “small-input small-state” stability, the complicated computations of perturbation bounds appeared in Sussmann et al (1994) are avoided. With the suggested method, a robust stabilizing control law is presented for the well-known translational oscillator with rotating actuator (TORA).

This paper considers the stabilization of a class of uncertain chaotic systems. A robust adaptive sliding-mode controller is proposed to suppress the chaotic systems with uncertain systematic parameter vectors and unknown bound on external disturbances. The obtained systems have the desired sliding-mode dynamics, which prescribes the asymptotic stability and robustness against uncertainties. The adaption laws, designed for identification of unknown parameters, are convergent with the Lyapunov stability theory. Finally numerical simulation of Genesio-Tesi system and Lorenz system verifies the effectiveness of this proposed control scheme.
