Abstract

The focus of this paper is the air fuel ratio control of spark ignited engines. It is known that for an efficient removalof the pollutants from the exhaust gases, air fuel ratio has to be kept within a narrow band around the stoicometricratio, which represents the condition where the air amount is perfectly matched with the fuel amount for a completeburn. The main challenges for this control problem are the inherent time delay of the system and uncertaindynamics. In this paper, employment of a high performance adaptive controller, which explicitly compensates for thedelays without causing excessive oscillations, is proposed. The performance of this controller is demonstrated viasimulation studies. To emphasize the importance of delay compensation, the controller is compared with the closedloop model reference adaptive controller, which do not have explicit delay compensation.

Özet

Bu makalenin konusu buji ateşlemeli içten yanmalı motorların hava yakıt karışımı kontrolüdür. Egzoz gazlarındaki çevre kirliliğine sebep olan maddelerin verimli bir şekilde temizlenebilmesi için hava yakıt karışımının tam yanmanın sağlanacağı seviyelerin çok dar bir bandında tutulması gerektiği bilinmektedir. Bu kontrol problemini zorlaştıran iki ana etken sistemdeki zaman gecikmeleri ve belirsiz dinamiklerdir. Bu makalede bu problemin çözümü için yüksek performanslı ve zaman gecikmelerini telafi eden, telafi ederken de aşırı salınımlara sebep olmayan bir uyarlamalı kontrolcü kullanılması önerilmektedir. Bu kontrolcünün performansı simülasyon çalışmaları ile gösterilmiştir.
