Adaptive Fuzzy PID Arithmetic Applied in Water Tank Temperature Control

Abstract

As the development of the modern workshop, the demand for water supply and heating system is more and more important. This paper comes from the faw-volkswagen company’s construction project about the automatic water supply system of one of its workshop. For many reasons, the conventional PID control can't satisfy the workshop’s demands for the certain temperature, after a careful research of the system, we utilize the principle of fuzzy PID adaptive control to design a fuzzy PID controller, then put it into the water tank heater’s controlling, through the practice, we find the controller has a good robust property and reached the practical production needs.
