앞먹임 신경회로망을 이용한 HSDI Common-Rail 인젝터의 파라미터 추정 및 모델링

This study presents the process of the solenoid parameter estimation of an common-rail injector for HSDI(High Speed Direct Injection) diesel engines. The EMF(Electromotive Force) and solenoid inductance are the major parameters for presenting the injector dynamics, and also these parameters are estimated by using a multi-layer feedforward artificial neural networks(ANN) The performances of parameter estimators are verified by the simulation with Injector model. The feasibility of this methodology is closely examined through the simulation in the Various operating points of injector The simulation results have revealed that estimated parameters show favorable agreements with the common-rail injector model.
