Worst-case Uncertain Parameter Combinations for Flight Control Systems Analysis
نویسندگان
چکیده
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 trimmed and linearized numerically, is required. The capability of the proposed approach to identify worst-case uncertain parameter combinations is demonstrated. The approach is compared with classical analysis methods via the robustness analysis of a control law for a Boeing 747 transport aircraft. Copyright © 2002 IFAC.

Robustness Analysis Applied to Autopilot Design Part 1: -analysis of Design Entries to a Robust Flight Control Benchmark
Analysis is a powerful tool for the assessment of the stability of uncertain parametric systems by means of the Structured Singular Value. The peak upper bound value of over a frequency range provides information on the stability margin of a system for given variations of uncertain parameters, while the computed lower bound on allows to obtain worst-case parameter combinations destabilizing the...
متن کاملComputation of Worst-case Pilot Inputs for Clearance of Flight Control Laws
In this paper, global optimisation and nonlinear simulation are used to search for the worst-case control demands which may be input by a pilot flying a modern high performance aircraft with a full authority flight control law. The flexibility of global optimisation is exploited to simultaneously search for worst-case pilot inputs and worst-case combinations of uncertain parameters in the nonli...
متن کاملMixed Μ-analysis Applied to the Attitude Control of the Metop Spacecraft
Mixed-μ analysis (hereafter also called worst-case analysis) techniques have become a powerful practice for supporting the control system design process on complex, multivariable, uncertain, time-varying and even non-linear systems. The motivation for the adaptation of such tools to space problems originated from the fact that large spacecraft or space structures exhibit low-frequency (quasi) u...
متن کاملWorst Case Output of Uncertain Systems, Report No. 2347
The numerical solution of the problem treated in this paper is an important step within a couple of recently developed controller-design procedures, dealing with multivariable or uncertain systems subject to hard-bounded control signals. We determine the worst case output amplitude of stable systems, excited with an input signal that is bounded in amplitude and rate. In the case of SISO systems...
متن کاملRobustness Analysis of Magnetic Torquer Controlled Spacecraft Attitude Dynamics
This paper describes a systematic approach to the robustness analysis of linear periodically time-varying (LPTV) systems. The method uses the technique known as Lifting to transform the original time-varying uncertain system into linear fractional transformation (LFT) form. The stability and performance robustness of the system to structured parametric uncertainty can then be analysed non-conse...
