| Abstract: | The temperature control and resistivity test system for crystallization process of amorphous material are designed.The control algorithm and the configuration of the hardware and software for the system based on microcontroller are introduced.In the system,the algorithm of combined self-tuning for temperature control that can satisfy simultaneously the performances of servo-tracking is proposed.In addition,the four-probe measurement approach that can overcome effect of contact and lead wire resistance is used.The result of the practical application shows that the system approaches the requirement for the study of crystallization process. |
