Streszczenie:

W pracy przeanalizowano możliwość wykorzystania nowych deskryptorów sygnału ciśnienia do sterowania wybranym obiektem. Odchylenia wartości sygnału ciśnienia od ich wartości średnich zostały wybrane jako przykładowy deskryptor. Jako obiekt referencyjny wybrano silnik Diesla zasilany olejem napędowym lub biopaliwami. Sygnał ciśnienia w cylindrze (pc) rejestrowano podczas procesu spalania.

Abstract:

This paper analyses the option of using pressure signal new descriptors for controlling a selected object. Pressure signal deviations from the pressure mean values were selected to be the example descriptors. Diesel fuelled with mineral- and bio-fuels was chosen to be the reference object. The in-cylinder pressure signal (pc) was recorded during the combustion process.
