Linear Parameter-Varying Control of a Ducted Fan Engine
Parameter-dependent control techniques are applied to a thrust vectored ducted fan engine. The synthesis technique is based on the solution of Linear Matrix Inequalities and produces a controller which achieves speci ed performance against the worst-case time variation of measurable parameters entering the plant in a linear fractional manner. Thus the plant can have widely varying dynamics over...
متن کاملComparison of Nonlinear Control Designs for a Ducted Fan Model
In this paper we compare diierent nonlinear control design methods by applying them to the planar model of a ducted fan engine. Those design can be divided into two steps. The rst step requires the derivation of a Control Lyapunov Function (CLF), while the second involves using an existing CLF to generate a controller. The main premise of this paper is that by combining the best of these two ph...
متن کاملNoise Source Identification for Ducted Fan Systems
Understanding combustion noise source mechanisms, designing efficient acoustic liners and optimising active control algorithms for noise reduction requires the identification of the frequency and modal content of the combustion noise contribution. Coherence-based noise source identification techniques have been developed which can be used to identify the contribution of combustion noise to near...
متن کاملComparison of nonlinear control design techniques on a model of the Caltech ducted fan
In this paper we compare di!erent nonlinear control design methods by applying them to the planar model of a ducted fan engine. The methods used range from Jacobian linearization of the nonlinear plant and designing an LQR controller, to using model predictive control and linear parameter varying methods. The controller design can be divided into two steps. The "rst step requires the derivation...
متن کاملActive control of fan noise on a UHB engine
The model developed in this work was used to investigate the potential that active noise control techniques have for reducing fan noise on an ultra high bypass (UHB) turbofan engine. Active noise control is expected to perform differently on a UHB turbofan engine than on a conventional turbofan engine since the short and wide inlet duct inherent to the UHB engine promotes radiation from evanesc...
