Abstract
A design method for pre-compensator in frequency domain of aeroengine multivariable control system based on diagonal dominance and the method of linear matrix inequalities (LMI) is presented. The conception of LMI and the design in frequency domain of diagonal dominance achieving pre-compensator are connected by bounded real lemma (BRL), and this method is aimed at reducing the effects of interactions in aeroengine multivariable systems. The improvement in reducing the interactions and the order of the controller is verified by simulation.
