Abstract

In order to achieve stable control of temperature in the process control, a system based on LabVIEW platform has been designed which can switch between fuzzy controller and PID controller, with the advantages and disadvantages of PID and fuzzy algorithm taken into account. In this paper, the PID parameter self-setting principle which is based on ASTROM limit cycle of law is also employed. The experiment results show that, the proposed method which combines fuzzy algorithm and PID control method, implemented by flexible online programming based on LabVIEW, can achieve high precision and strong robustness in the industrial applications.
