Abstract

This study used fuzzy logic theory to design a temperature controller, which was used for a butterfly laser module. Experimental results showed that shorter settling time and less steady state error can be achieved compared with a commercial PID controller. And no overshoot was observed in the control process. In addition, response time to achieve stable temperature was faster and more accurate temperature control can be achieved. This indicated the performance of laser module could be enhanced and reliability could be increased as using fuzzy logic controller on temperature control of laser module.
