| Abstract: | The design of robust controller for hypersonic vehicle and the simulation of the light control system are investigated. The selection of weighting function matrixes for general tracking control problems is discussed. LMI technique is a kind of effective tool for studying all kinds of problems in the field of control theory and application. The problems of robust control analysis and synthesis can be converted to solving LMI problems. A robust flight controller is designed by using linear matrix inequality(L... |
