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.

利用模糊逻辑理论改进激光模块的温度控制

本研究运用模糊逻辑理论设计了一种温度控制器，并应用于蝴蝶激光模块。实验结果表明，与商用PID控制器相比，该控制器的稳定时间更短，稳态误差更小。在控制过程中未观察到超调现象。此外，响应时间更快，达到稳定温度，可以实现更精确的温度控制。说明采用模糊控制器对激光模块进行温度控制，可以提高激光模块的性能和可靠性。
