An observer-based controller design method for improving air/fuel characteristics of spark ignition engines

In the urban traffic mode, the engine is known to be operated mostly in a transient state. However, the wide operating range, the inherent nonlinearities of the induction process and the large modeling uncertainties make the design of the fuelinjection controller very difficult. Even though a sliding mode fuel-injection control method is in good agreement with the characteristics of the system,...

Air-Fuel Ratio Control of a Lean Burn SI Engine Using Fuzzy Self Tuning Method

Reducing the exhaust emissions of an spark ignition engine by means of engine modifications requires consideration of the effects of these modifications on the variations of crankshaft torque and the engine roughness respectively. Only if the roughness does not exceed a certain level the vehicle do not begin to surge. This paper presents a method for controlling the air-fuel ratio for a lean bu...

Diagnosis of the disease using an ant colony gene selection method based on information gain ratio using fuzzy rough sets

With the advancement of metagenome data mining science has become focused on microarrays. Microarrays are datasets with a large number of genes that are usually irrelevant to the output class; hence, the process of gene selection or feature selection is essential. So, it follows that you can remove redundant genes and increase the speed and accuracy of classification. After applying the gene se...

Air-to-Fuel and Dual-Fuel Ratio Control of an Internal Combustion Engine

Air-to-fuel (A/F) ratio is the mass ratio of the air-to-fuel mixture trapped inside a cylinder before combustion begins, and it affects engine emissions, fuel economy, and other performances. Using an A/F ratio and dualfuel ratio control oriented engine model, a multi-inputmulti-output (MIMO) sliding mode control scheme is used to simultaneously control the mass flow rate of both port fuel inje...

Multi-sensor Target Recognition Based on Relative Ratio Method

The aim of this study is to propose a new target recognition method for the multi-sensor with multiple characteristics indexes. Coefficient of variation is used to determine the weights of characteristic indexes. The conceptions of ideal optimal and negative ideal vectors are given first and then normalized relative ratio is used to comprehensive evaluation value. Hence the rule of target recog...
