Abstract

U ovom radu opisana je identifikacija nelinearnog modela dvotaktnog benzinskog
motora DLE-111 za bespilotnu letjelicu. Model je identificiran pomocu MLP
(Multi Layer Perceptron) neuronske mreže. Ulaz u neuronsku mrežu je trenutni
gas izražen u postotku i 5 prethodnih stanja (5 parova gas-brzina) kako bi se
simulirala dinamika sustava. Izlaz je trenutna brzina. Odstupanja brzine modela
motora ne prelaze 30 okretaja u minuti. To je prihvatljivo jer se brzina motora
krece od otprilike 1000 do 7500... More okretaja u minuti. Less

Abstract (english)

In this paper identification of nonlinear model of 2-stroke internal combustion
DLE-111 engine for UAV (Unmanned Aerial Vehicle) is described. Model is
identified with MLP (Multi Layer Perceptron) neural network. Neural network
input is current percentage of throttle and previous 5 throttle-speed pairs, to
simulate dynamics of the system. Output is current speed. Engine model speed
deviation do not ovestep 30 rpm. This deviation is acceptable because the real
engine speed range is... More approximatley from 1000 to 7500 rpm. Less
