High Dynamic Engine-Dynamometer Identification and Control

چکیده
In this paper, a high dynamic test-bed control problem for high dynamic vehicle simulation is studied in order to improve the tracking of speed and torque. As the system is nonlinear and square (2x2) with two inputs and two outputs, a multi-input multi-output (MIMO) system-identification problem is discussed. The test-bed data are processed using a fast frequency domain methodology to build a nominal linear plant and a perturbation model. Based on this perturbed plant, the CRONE Control-System Design approach (a fractional order of differentiation based methodology) is used to design a robust MIMO controller, which maintains performance around a wide set of operating points. Finally, experimental results show the relevance of the proposed methodology.

Investigation of Swirling and Tumbling Flow Pattern of Spark Ignition Engine
Gas motion within the cylinder is one of the major factors that control the combustion process in spark ignition engine. It also has significant impact on heat transfer. Both the bulk gas motion and the turbulence characteristics of the flow are important and governing the overall behavior of the flow. An arrangement for obtaining a stratified charge, using port injection, is proposed for a ...
متن کاملA Transient Hydrostatic Dynamometer for Single Cylinder Engine Research
A new high-bandwidth transient dynamometer has been designed and is being built for application to a single-cylinder research engine. The goal of this system is to accurately reproduce all of the dynamic, instantaneous torques that this single-cylinder would experience if it were in a multi-cylinder engine. This is accomplished by calculating these instantaneous torques in real time using a det...
