The Research On Digital Governor System Of DCS-Based Ship-diesel Generator Set

The research on digital governor system of DCS-Based (Distributed Control System) ship-diesel generator set is a subproject of the research of ship DCS-based diesel generator set which is one of the Transport Ministry's great scientific subjects. This article is written by means of the practical research of the subproject.In this paper the method of the design and fracture of a kind of digital governor is elaborated. By means of the practical research on the scene of the development of DCS, on basis of defined own network protocol, the communication interface between high-level and low-level computers is made. UNICOM. OCX control is developed. That breaks the limitation which Microsoft Visual Basic's MSComm control is only used ASCII in the series data transmissions and improves the efficiency of data transmissions.The governor can work automatically adopting 2-dimension fuzzy control rule which can be adjusted by itself. In a sense, the echoing speed and stable character have been improved in the system. Because of the limitation of the experimental conditions, execution mechanism of the system can not be reached to the perfection.
