This paper deals with robust control problems for large envelope flight control systems. Based on data fitting, a class of uncertainty model is improved to describe the flight control systems with wide operation range. The uncertainty model can reflect both the time-varying characteristic and the fitting error. Robust stability criterion and stabilizers design method via state feedback are proposed...
The control accuracy of flexible satellite attitude would be impacted by the large scale changes of the dynamic parameters caused by the temperature and structural deformation, when flight in orbit. Considering the case of the existence of quality parameters uncertainty, flexible modal frequency uncertainty and external disturbance, the paper studies the flexible satellite attitude dynamics and the...
