Application & Research Of Fuzzy Control In Manufacture Of Fosfomycin Sodium

This paper is grounded on the project of tackle key to problem which is initiated by Nation Labor Department and Northeast General pharmaceutical Factory , rely on "identifying of a serious danger source and control system in produce process of fosforncin sodium" by Automation Control Institute of Dalian Maritime University. We replace manual operation by the computer system in ZhangShi pharmaceutical company which is one of factories of Northeast General pharmaceutical Factory. We aimed at discontinuity, uncertainty, instability in intermission produce control. Because serial controllers and PID controller haven't good effect on this type system and the control parameters are difficult to be determined. We apply fuzzy controller to the process which includes three subsidiary constant temperature process. In the course of designing fuzzy control, we not only borrow ideas from experience of good fuzzy controllers running in other industrial process, but also reconstruct the design ways of serial controllers, when determining the fuzzy rules, we refered to lots of practical experience from engineers and workers in the spot. In the end our fuzzy controller can run successfully.This computer control system with fuzzy controllers has research the request in technics. The success is a good test in changing manual operation in pharmaceutical factories and enhancing the safety, material consume and enhancing the radio of production. It also gives a good example which can be used in chemical industry, food industry and drink industry.
