Abstract :
This paper discusses the time-domain model identification problem for aeroengine hydraulic actuator. Against the case that the dynamics of hydraulic actuator is nonlinear, an experiment method is proposed to obtain data for model identification. It is also proofed that the coordinate of experiment data should be transformed before model identification. Then the model can be identified based on Matlab toolbox. In addition, two simulation structures are suggested and compared for model validation and simulation analysis. At last, an example is carried out to demonstrate the effectiveness of the proposed method.
