Gabsys: Using Genetic Algorithms to Breed a Combustion Engine
نویسندگان
چکیده
|Most engineering systems are designed on the basis of a steady, or static, state. However, dynamic e ects must also be considered. This paper presents GABSys (Genetic Algorithm-Bond Graph System), a tool for approximating design optimality for multi-dimensional dynamic systems. Although GABSys does require the assistance of an engineer, it can be used to \automatically" generate solutions to design problems. We illustrate GABSys' utility by using it to design a 2-stroke Combustion Engine. GABSys begins with behavioral requirements expressed in a bond graph and uses genetic algorithm techniques to produce a design that meets the speci ed behavioral requirements. Keywords|Genetic Algorithms, Bond Graphs.

متن کاملA Method for Pre-Calibration of DI Diesel Engine Emissions and Performance Using Neural Network and Multi-Objective Genetic Algorithm
Diesel engine emission standards are being more stringent as it gains more publicity in industry and transportation. Hence, designers have to suggest new controlling strategies which result in small amounts of emissions and a reasonable fuel economy. To achieve such a target, multi-objective optimization methodology is a good approach inasmuch as several types of ...
متن کاملOptimal Idle Speed Control of a Natural Aspirated Gasoline Engine Using Bio-inspired Meta- heuristic Algorithms
In order to lowering level of emissions of internal combustion engines (ICEs), they should be optimally controlled. However, ICEs operate under numerous operating conditions, which in turn makes it difficult to design controller for such nonlinear systems. In this article, a generalized unique controller for idle speed control under whole loading conditions is designed. In the current study, in...
