Abstract: The near deadbeat control design was applied to an aeroengine speed simulation system for flight handling simulation.High power demand of the aeroengine speed simulation system can be met by adopting a type of electrohydraulic pump controlled motor system.But the desired dynamic properties are difficultly obtained under the condition of large step imput amplitude.According to the idea of deadbeat control,a method of quasi-deadbeat control design is proposed to overcome the difficulty.The experiments testified the effectiveness of the presented design.
