Abstract :
A laboratory system for surface temperature control has been developed. The system uses optical temperature measurement methods and a scanned heat source, and is characterized by a large number of heating zones with strong interactions between zones. This raises the challenge of finding a computationally simple, yet effective control algorithm. The best-system performance resulted from using a gain adjusted PID controller, in which each heating zone is treated independently
