A Comprehensive Robust Adaptive Controller for Gust Load Alleviation
The objective of this paper is the implementation and validation of an adaptive controller for aircraft gust load alleviation. The contribution of this paper is the design of a robust controller that guarantees the reduction of the gust loads, even when the nominal conditions change. Some preliminary results are presented, considering the symmetric aileron deflection as control device. The prop...
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...
متن کاملHybrid Controller for Gust Load Alleviation and Ride Comfort Improvement Using Direct Lift Control Flaps
In this paper two robust H∞ feedback control laws are designed, one for active wing bending damping, and one for active damping of the wing and hull bending modes. For the latter, not only symmetrically commanded ailerons are used, but also the elevator and direct lift control (DLC) flaps. The control objective of these feedback laws is the reduction of fatigue of the wing roots, as well as the...
متن کاملRobust Control Synthesis for Gust Load Alleviation of Large Aeroelastic Wind Turbine Models
This paper introduces a methodology for the design of gust load control systems directly from large aeroelastic models. Firstly, a state-space representation of the vortex particle unsteady aerodynamics suitable for control synthesis is implemented. Secondly, through the use of robust controllers, large reductions in loadings are demonstrated. Thirdly, controllers synthesized from models of coa...
