The Study Of Fuzzy Variable Frequency Control System For Constant Pressure

The fuzzy control system for constant pressure is a kind of automatically control system which applied single-chip microcomputer real-time control and fuzzy control tecnology to realize high speed, high reliability and automatically constant pressure control. The system simultaneously used the technique of computer, electron as well as single-chip microcomputer, and solved the key problem brought about by the pump's high speed revolving all the time.That is, the electrical energy's waste,which existed in the water supply system of the city and the high building.At the same time overcome the shortcomimg of long reaction time of the traditional water supply system ,varied frequency at low speed,made use of large area,and consume a lot. The study provided a practical method for constant pressure water supply.The paper has introduced the fuzzy control system's structure, working principle and design idea for software, At the same time,the technique of fuzzy control principle associated and serial port active VB as well as variable velocity variable frequency is expounded.
