Abstract:Some characteristics such as nonlinearity, time variant and time delay of an industrial temperature control system have great influence on the fastness and accuracy of temperature control. This may result in great danger in practical production. How to realize accurate infrared temperature measurement of a kiln body and how to use an adaptive fuzzy PID algorithm for corresponding control are presented. Some results simulated by Matlab are shown. The results show that this kind of algorithms can play a critical role in the performance improvement of an infrared temperature measurement system for a kiln body.
