Distributed Model Predictive Control with Actuator Saturation for Markovian Jump Linear System

引用

IEEE/CAA Journal of Automatica Sinica 2015年第4期2卷 374-381页

作者： Yan Song Haifeng Lou Shuai Liu Department of Control science and Engineering University of Shanghai for Science and TechnologyKey Laboratory of Modern Optical SystemEngineering Research Center of Optical Instrument and SystemMinistry of Education Business School University of Shanghai for Science and Technology

This paper is concerned with the distributed model predictive control (MPC) problem for a class of discrete-time Markovian jump linear systems (MJLSs) subject to actuator saturation and polytopic uncertainty in system matrices. The global system is decomposed into several subsystems which coordinate with each other. A set of distributed controllers is designed by solving a min-max optimization problem in terms of the solutions of linear matrix inequalities (LMIs). An iterative algorithm is developed to achieve the online computation. Finally, a simulation example is employed to show the effectiveness of the proposed algorithm. © 2014 Chinese Association of Automation.

Thermal Stress-Induced Birefringence in Borate Glass Irradiated by Femtosecond Laser Pulses

引用

Chinese Physics Letters 2005年第10期22卷 2626-2629页

作者：戴晔余昺鲲鲁波邱建荣阎晓娜姜雄伟朱从善 Department of Physics College of Sciences Shanghai University Shanghai 200444 shanghai Institute of Optics and Fine Mechanics Chinese Academy of Sciences Shanghai 201800

Thermal stress-induced birefringence in borate glass which has been irradiated by 800-nm femtosecond laser pulses is observed under cross-polarized light. Due to the high temperature and pressure formed in the focal volume, the material at the edge of the micro-modified region is compressed between the expanding region and the unheated one, then stress emerges. Raman spectroscopy is used to investigate the stress distribution in the micro-modified region and indicates the redistributions of density and refractive index by Raman peak shift. We suggest that this technique can develop waveguide polarizers and Fresnel zone plates in integrated optics.
