Based on Lyapunov-Razumkhin approach  the robust controller is designed by solving a set of LMIs. In the controller design procedure there are not any requirements for the derivative of the delay  which allows fast time-varying delay. Numerical example shows the effectiveness of the proposed method. 2009 ETP.   Based on Householder transform of the Zernike polynomial wave front fitting method to solve active optics correction force (EI CONFERENCE) 会议论文  OAI收割 Infrared Materials, Devices, and Applications, November 12, 2007 - November 15, 2007, Beijing, China 作者:  Wu X.-X. 收藏  |  浏览/下载：27/0  |  提交时间：2013/03/25 Corrective force solving is a critical technology of the active optics. A method to solve active optics corrective force is introduced  which is based on Householder transform of Zernike polynomial wave front fitting  this method is different from the traditional least square method and Gram-Schmid orthogonal method  because it does not bring ill-conditioned polynomial without constructing normal equation  so it can avoid calculation error  wave front fitting is precision. Based on the coefficient of the Zernike polynomial and the response function of the each actuator  the stiffness matrix of the primary mirror is built  and then adopting the damp least square method to calculate corrective force. Based on this method  cp400m test mirror is simulated many times  the calculation result approve: if the Householder transform is adopted  wave front fitting is precision  the result is stabilization and corrective effectiveness is better.   Numerical Simulation of Active Suppression of Rotating Stall in Axial Compression Systems 期刊论文  OAI收割 JOURNAL OF THERMAL SCIENCE, 1995, 卷号: 4, 期号: 4, 页码: 231,242 Jun Hu; Leonhard Fottner 收藏  |  浏览/下载：12/0  |  提交时间：2013/03/13 active suppression  rotating stall  surge  stabilization effectiveness  system parame ters.   Numerical Simulation of Active Suppression of Rotating Stall in Axial Compression Systems 期刊论文  OAI收割 JOURNAL OF THERMAL SCIENCE, 1995, 卷号: 4, 期号: 4, 页码: 231,242 作者:  Jun Hu;  Leonhard Fottner   |  收藏  |  浏览/下载：23/0  |  提交时间：2013/03/13 Active Suppression  Rotating Stall  Surge  Stabilization Effectiveness  System Parame ters.
