We design the cold light source in the measurement of near infrared spectroscopy. Cold light source consists of high-power op amp OPA549 high current constant current source and proportion integral differential (PID) control algorithm. As is shown in the experimental results  the method is better  the overshoot is very small  the stability is excellent in the process of soft-start. While light intensity was able to meet the requirements of near-infrared instruments to measure. 2011 IEEE.   Development of Constant Current Source for SMA Wires Driver Based on OPA549 会议论文 LIFE SYSTEM MODELING AND INTELLIGENT COMPUTING, PT I, 2010-09-17 作者:  Shao, Yong[1];  Jiang, Enyu[2];  Huang, Quanzhen[3];  Zeng, Xiangqiang[4] 收藏  |  浏览/下载：3/0  |  提交时间：2019/04/30 smart structures  shape memory alloy  constant current driver  design proposal
