英文摘要	The problem of disturbance rejection and control allocation with an uncertain control effectiveness matrix is investigated in this paper for a flight control system. An H(2)/H(infinity) feedback controller is designed to produce the three axis moments and simultaneously suppress disturbance noise. A feedforward controller is used to track the reference signals. Under the condition of uncertainty included in the control effectiveness matrix, a robust least-squares scheme is employed to deal with the problem of distributing the three axis moments to the corresponding control surfaces. The proposed robust least-squares control allocation is studied for both unstructured and structured uncertainties. To illustrate the effectiveness of the proposed scheme, a simulation for an experimental satellite launch vehicle model is conducted. Comparisons of robust least-squares control allocation and pseudoinverse control allocation are presented. Results show that a disturbance is rejected and robust least-squares control allocation is effectively robust to uncertain control effectiveness matrix.; http://gateway.webofknowledge.com/gateway/Gateway.cgi?GWVersion=2&SrcApp=PARTNER_APP&SrcAuth=LinksAMR&KeyUT=WOS:000296824900003&DestLinkType=FullRecord&DestApp=ALL_WOS&UsrCustomerID=8e1609b174ce4e31116a60747a720701 ; Engineering, Aerospace; Instruments & Instrumentation; SCI(E); EI; 17; ARTICLE; 6; 1632-1643; 34
