第26届中国控制与决策会议

作者： xingwen liu College of Electrical and Information Engineering Southwest University for Nationalities of China

Dynamical systems in the real world are always subject to various disturbances. This paper studies the dynamics of delayed discrete-time linear systems with decaying disturbances. It is first shown that if an unforced linear system is exponentially stable, then the disturbed system has a dynamical property like the exponential stability if the disturbance decays at an exponential rate, and has a dynamical property like the asymptotic stability if the disturbance asymptotically approaches to zero.

This paper concerns about lag-consensus of linear multiagent systems employing pinning control. A periodic data sampling method is used to design the leader-following lag-consensus control law. A sufficient condition of lag-consensus is presented by constructing a delay-dependent Lyapunov-Krasovskii functional. The feedback control gain matrix is designed by solving linear matrix inequalities. Finally, a numerical example is provided to demonstrate the proposed theoretical result.

Stability Analysis of Continuous-Time Almost Periodic Piecewise Linear Systems with Dwell Time Uncertainties

第43届中国控制会议

作者： Bingyi Wei xingwen liu Yuanyuan Li Center for Intelligent Complex Systems College of Electrical Engineering Southwest Minzu University

Exponential stability analysis of continuous-time almost periodic piecewise linear systems(CTAPPLSs) is addressed in this paper. Since CTAPPLSs are composed of subsystems activated cyclically within a fundamental period, they can be modeled as switched systems with a cyclic switching rule. By introducing the extended systems of orignal systems and employing a multiple discontinuous convex Lyapunov function, some exponential stability criteria are presented. Note that a degree parameter d is contained in these criteria, and that conservatism of stability condition reduces as d increases. Finally, numerical simulations are conducted to show the effectiveness of the proposed results.

This paper addresses the issue of exponential stability of discrete-time almost periodic piecewise linear systems(APPLSs) with dwell time uncertainties under mode-dependent average dwell time(MDADT) switching signal. Considering dwell time uncertainties in discrete-time APPLSs, multiple piecewise convex homogeneous Lyapunov function(MPCHLF) is constructed. In the case where the switching instants within each period are unknown but lie within a certain range, a sufficient exponential stability condition for the discrete-time systems is proposed. Finally, a numerical example validates obtaining low conservatism using the proposed approach.

The problem of asynchronous switching control is studied for a class of discrete-time switched delay systems with mode-dependent average dwell time switching, taking the time delay constraints of mode-dependent controllers into consideration. By constructing appropriate Lyapunov functionals, sufficient conditions that guarantee stability of the considered systems with mode-dependent average dwell time switching are obtained. Based on the stability result, existence conditions of the controllers are formulated in terms of a set of linear matrix inequalities. A numerical example is given to demonstrate the proposed theoretical result.

This paper addresses robust stability and stabilization problems of uncertain linear systems with time-varying *** constructing a new Lyapunov-Krasovskii functional（LKF） called delay-mode-based Lyapunov-Krasovskii functional, some novel robust delay-dependent stability and stabilization criteria are developed. Due to the fact that the considered time delay system has different characteristics in different delay subintervals, this method may lead to less conservative results by constructing LKF in each delay subinterval. A numerical example is given to show the effectiveness.

准确获取流域土壤湿度(MS)的初始值及过程状态,对提高实时洪水预报精度具有重要意义和实用价值。从新安江模型参数的物理意义出发,基于站点墒情数据和CLDAS土壤湿度数据构建点面转换模型(WKNN),将点面转换后的实时面尺度MS作为观测数据,采用集合卡尔曼滤波法同化新安江模型预报的MS过程,在五强溪区间流域进行实时洪水预报应用。结果表明:WKNN作为点面转换工具,能够捕捉到不同土层MS的点面关系,具有较好的适用性;较不同化模式,多层MS同化后的平均径流深相对误差下降了12.67%,平均确定性系数提高了41.82%;MS的实时同化可以显著降低汛初期洪水的预报误差,提高洪水预报精度,且多层同化较单一层同化效果更优。
