一种飞控系统不确定性建模方法及其鲁棒控制
Uncertainty modeling and robust stabilization for large envelope flight control systems
摘要
Abstract
We present a modeling method tor uncertainty in the large envelope thglat control systems to reduce the conservatism on system description. This method is based on the normalization of perturbation parameters and the data fitting at various operation points; the fitting error is treated as the norm~bounded uncertainty. The existence conditions and the design method for dynamic output feedback stabilization controllers are proposed on the basis of quadratic stability criterion; the perturbation parameters are properly matched. The approach for estimating the perturbation ranges is put forward via the convex optimization under the condition that the resulting closed-loop systems are robustly stable. This approach presents the ranges in the 2-norm form and establishes the relationship between perturbation parameters and the quadratic stability. All the formulas are derived in the form of linear matrix inequalities and can be realized conveniently. Simulation results of the flight control system demonstrate the effectiveness and feasibility of the proposed methods.关键词
