Multi-factor predication of diesel engine by using artificial neural networks

Abstract

The paper presents an algorithm which combining a neural network observer, it give more flexible and accurate control on the engine operation. In recent year, several researchers already proposed the algorithm which is based on a model-based adaptive control and uses artificial neural networks, and they assumed engine system is also controled by severe non-linear dynamics and their modelling. Especially, the neural network model observer is related with effective torque and brake torque. And they also proposed the model predictive control strategy which uses information multivariables and considers engine dynamics to do multi-step ahead prediction, and is adapted in on-line mode to cope with system uncertainty and time varying effects. Even though they already proposed this kind of nonlinear model method, they never think about combining all non-linear factors together. In this paper, we proposed a well-trained artificial neural networks which used as a predictive model for a combination of non-linear factors. Finnally, experiments shows the predicative results and experimental results are in a good agreement.

Neural Predictive Controller Based Diesel Injection Management System for Emission Minimisation

“…The control design consists of two parts as H∞ (infinity) LFT control design and the anti-windup compensator design. Xiao (2010) proposed the use of artificial neural network as a predictive model for combination of non-linear factors of engine. ANN model estimates power, torque, fuel consumption and specific fuel consumption.…”

Strength Analysis of Diesel Engine Crankshaft Based on Flexible Multi-Body Dynamics

“…The diesel engine is widely used in national product as the power equipment, it is important to ensure the reliability of the diesel engine [1]. Fatigue damage is one of the main destroy form of the diesel engine parts and components which absorb periodic dynamic loads and need to cause enough attention.…”
