Worst-case Uncertain Parameter Combinations for Flight Control Systems Analysis

This paper presents a new technique for generating linear fractional transformation based uncertainty models for use in the robustness analysis of flight control systems using the structured singular value . The proposed approach does not require closedform linear expressions for the aircraft dynamics – only a non-linear software model of the closed loop aircraft, which can be efficiently trimm...

Worst-case analysis of finite-time control policies

Finite-time control policies are common in batch and semibatch operations. A novel approach is proposed that quantifies the impact of parameter and control implementation inaccuracies on the performance of such control policies. This information can be used to decide whether more experiments are needed to produce parameter estimates of higher accuracy, or to define performance objectives for th...

Worst-Case Linear Discriminant Analysis

Dimensionality reduction is often needed in many applications due to the high dimensionality of the data involved. In this paper, we first analyze the scatter measures used in the conventional linear discriminant analysis (LDA) model and note that the formulation is based on the average-case view. Based on this analysis, we then propose a new dimensionality reduction method called worst-case li...

Generalized preview and delayed H∞ control: output feedback case

A generalized H∞ control problem, which covers preview and delayed control strategies, is discussed in the output feedback setting. By introducing analytic solutions to the corresponding control/filtering operator Riccati equations, the solvability is clarified based on the fundamental solutions to ordinary differential equations. The solutions obtained here enable us to deal with important cla...
