| Abstract: | Based on the achievements of previous works,the following problems areincluded in this paper.Abrief introduction of eigenstructure assignment method andsingular perturbation method of flight control system design is given. It introduces mini-mum singular value of return difference matrix to calculate stability margin of closedloop system. Finally,one design example of direct lift control is presented to illustratedabove method. |
