Design of intelligent controllers for electronic speed regulation of a diesel engine

Abstract

An investigation pertaining to identification and expert control design of a diesel engine system is carried out. Diesel engines are known for their high versatility, making them useful in a wide range of industrial applications. Despite several of their attractive features, diesel engines suffer from highly nonlinear and time varying dynamics making them hard to control. The current study provides a means of comparing several types of controllers, some of which are adaptive based and others which are knowledge based. The main goal is to obtain the best possible performance in terms of speed regulation, robustness to load disturbances, and fuel efficiency. This is very helpful in gaining insights for designing a hierarchical based controller under which the system can switch smoothly from one controller to another depending on the operating conditions of the system.
