Robust Stability Analysis and Stabilization for Large Envelope Flight Control Systems
摘要
Abstract
Large envelope flight control systems are described in the form of polynomial related to perturbation parameter and norm-bounded perturbation. Both the time-varying characteristic and the uncertainty from fitting error are considered in this paper. The problem on robust stability analysis and stabilization for large envelope flight systems is concerned based on the concept of quadratic stability. Based on linear matrix inequality (LMI) approach,a quadratic stability criterion is addressed. Also this approach is employed to design a state feedback controller. Furthermore,a method on estimating the parameter perturbation range is addressed via convex optimization and it establishes the relationship between system parameter and performance. An example is given to illustrate the effectiveness of the method proposed in this paper.关键词
