Robust Property

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.

This paper show a parameter self-adaptive fuzzy PID controller which was designed by using fuzzy logical rules, and the rules aiming at characteristics of constant pressure water-supply system such as nonlinear, multi-parameters and long time delay. The controller can online auto tuning PID parameters to select the appropriate control parameters, depending on the working conditions for effective control of the water supply system water pressure regulator. The simulation results show that the control system response quick, over regulation measurement and transitional time is greatly reduced, oscillation time shorten, and the system has strong robustness and good stability.

System Requirements

In order to solve the air supply pressure instability problem in mine compressor, a fuzzy-PID controller is designed to be combined with conventional proportional-integral-derivative (PID) control and fuzzy control technology based on the programmable logic controller (PLC), where the compressor air supply system can achieve optimal control based on the system requirements and the actual usage, realizing air supply with constant pressure for compressor.
