OIL CONCENTRATION ESTIMATION SYSTEM AND METHOD USING HIERARCHY STRUCTURE FCM-TSK FUZZY INFERENCE

摘要

PURPOSE: An oil concentration estimation system and method, using hierarchy structure FCM-TSK fuzzy inference, are provided to enable a user to accurately estimate an initial value on spite of measuring environment change.;CONSTITUTION: An oil concentration estimation system comprises a first concentration estimation value output unit(100), a 45° scattering light reference signal difference value output unit(200), 90° scattering light reference signal difference value output unit(300) and a TSK fuzzy inference unit(400). The first concentration estimation value output unit outputs the first concentration estimation value. The 45° scattering light reference signal difference value output unit outputs the 45° scattering light reference signal difference value by using the first concentration estimation value and 45° sensor signal. The 90° scattering light reference signal difference value output unit outputs a 90° scattering light reference signal difference value by using the first concentration estimation value and 90° sensor signal. The TSK fuzzy inference unit outputs a final oil density value using the 90° scattering light reference signal difference value. The first concentration estimation value output unit comprises a 0° sensor signal corrector(21) and a 0° penetration model block(24).;COPYRIGHT KIPO 2012
