第二十四届中国控制会议

作者： He Liang, Duan Guangren (Center for control Theory and Guidance Technology Harbin Institute of technology. P. O. Box 416, Harbin. 150001. China)

In this paper, multiobjective control synthesis based on Hdisturbance attenuation blended with D -stability constraints on the closed-loop pole location is addressed for a class of systems containing linear fractional uncertainties. A state feedback controller is designed to achieve a compromise between the H-norm bound and pole constraints. Solutions to the problem are derived in terms of a family of linear matrix inequalities and are numerically tractable via LMI techniques. A numerical example demonstrates the effect of the proposed design approach.

H-infinity control with an alpha-stability constraint:a descriptor system approach

控制理论与应用（英文版） 2008年第2期6卷 115-121页

作者： Dabo XU Qingling ZHANG Key Laboratory of Integrated Automation of Process Industry Ministry of Education Northeastern University Shenyang Liaoning 110004 China

This paper deals with the problem of designing state or full-order output feedback H-infinity controllers satisfying an α-stability constraint. A descriptor system approach is adopted to derive linear matrix inequality （LMI） conditions of α-stability and H-infinity performance for linear time-invariant （LTI） systems, under which the multiobjective control laws can be constructed with a mix of H-infinity performance and α-stability. Being expressed in terms of a group of bilinear matrix inequalities, the design algorithm is numerically tractable via an LMI optimization method. A numerical example illustrates the feasibility and effectiveness of the proposed approach, and the results are also compared with those obtained by the well-known Lyapunov shaping paradigm （LSP）.

第二十三届中国控制会议

作者： Li Yinya, Sheng Andong, Wang Yuangang (Department of Automation, Nanjing University of Science and Technology, Jiangsu Nanjing, 210094, P. R, China)

A method on the design of multiobjective satisfactory PI controllers for second-order systems with time delay is proposed in this paper. The method is based on plotting stability boundary locus in the kp-ki plane. All stabilizing PI controllers parameters, which achieve the desired gain and phase margins, can be determined in the kp-ki plane. Performing a search on the entire compact closed stability region, PI controllers which satisfy the desired time-domain performance specifications can be fast calculated. More over, the necessary condition for the existence of a PI controller to simultaneously stabilize the open-loop unstable second-order time-delay systems is also derived. Examples are given to show the effectiveness of the method presented.

第30届中国控制与决策会议

作者： Defeng He Liangye Lu Xiulan Song College of Information Engineering Zhejiang University of Technology

This paper considers the multiobjective control problem with different criteria priorities and we propose a lexicographic multiobjective model predictive control(MO-MPC) scheme for a changing criteria prioritization of constrained nonlinear systems. Using the lexicographic approach, the solution to the MO-MPC problem is obtained by solving a sequence of single objective, constrained optimal control problem over a receding horizon. The proposed controller is always guaranteed feasibility for any changing criteria prioritization by the general terminal constraint. Asymptotic stability of the closed-loop systems is also proved by a Lyapunov function of the positive definite function with the highest priority. An example of a two-tank system control is used to illustrate the effectiveness of the scheme proposed here.
