摘要:
为了提高气溶胶激光雷达( ALD )的测量精准度,设计一套模拟光源来校准 ALD 的接收系统。将 BUCK 电路和嵌入式控制系统相结合,提出了一种高准确性、低功耗的 ALD 校准光源调节控制技术。首先,设计了 LED 光源的控制系统和 LED 恒流驱动的控制电路结构;其次,根据继电反馈控制和 Ziegler Nichols ( Z-N )法设计了 LED 工作电流的比例、积分和微分( PID )自整定算法;最后,通过实验验证了控制电路具有低功耗、高准确性的特点。
Abstract:
To effectively improve the measurement accuracy of aerosol lidar ( ALD ), a set of simulated light source needs to be designed to calibrate the receiver system of ALD.In this paper , a high-accuracy and low-power regulation control technique was proposed , which integrates a BUCK circuit and an embedded control system for regulating the calibration light source of ALD.First , the control system of the LED light source and the control circuit structure of the LED constant current driver were designed ; secondly , the proportional-integral-derivative ( PID ) autotuning algorithm for the LED operating current was designed , according to relay feedback control and the Ziegler-Nichols ( Z-N ) method ; finally , the control circuit was experimentally verified to exhibit low-power and high-accuracy characteristics.
