Robust stablization for a class of large envelope flight control systems

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 for flight control systems with the class of uncertainty. Moreover, a convex optimization method is provided to estimate the parameter perturbation range. Finally, a simulation example is given to illustrate that the method is feasible.
