Gust Load Alleviation Based on Model Predictive Control
Weight reduction is a typical design goal for modern aircraft. If gust encounters (as required by Certification Specification 25) are sizing conditions of parts of the airframe, this can be achieved (for example) by an active gust load alleviation system that reduces the gust load level down to the level of the next design condition, which might be the design loads from maneuver conditions. In ...
متن کاملGust Load Alleviation Control for Very Flexible Aircraft
This paper focuses on the development of a wind gust load alleviation control system for implementation in very flexible aircraft. The gust load alleviation system is designed using Linear Quadratic Gaussian (LQG) control techniques, and it is based on a nonlinear model of the coupled rigid-body and elastic modes of a very flexible aircraft. The nonlinear model contains the dynamics of the airc...
متن کاملPerformance Optimizing Gust Load Alleviation Control of Flexible Wing Aircraft
This paper details a control design for flexible wing aircraft that attempts to minimize the load induced by gust disturbance. Wing root bending moment is taken as an available measure of gust load and is used in a performance optimizing cost function to determine the load-alleviating control signal. However, both the disturbance signal and system matrices associated with wing root bending mome...
متن کاملAdaptive Feedforward Control for Gust Loads Alleviation
Active control techniques for the gust loads alleviation/flutter suppression have been investigated extensively in the last decades to control the aeroelastic response, and improve the handling qualities of the aircraft. Nonadaptive feedback control algorithms such as classical single input single output techniques (Schmidt & Chen, 1986), linear quadratic regulator (LQR) theory (Mahesh et al., ...
متن کامل-Optimal Gust Load Alleviation for a Flexible Aircraft
+2 (LQG), weighted-+2 and +∞ techniques are used to establish a nominal performance baseline for the vertical acceleration control of a B-52 aircraft model with flexibilities. The aircraft is assumed to be subjected to severe wind gusts causing undesirable vertical motion. The purpose of the controllers is to reduce the transient peak loads on the airplane caused by the gusts. Our designs accou...
