摘　　要：为了实现光电跟踪目标,用四象限探测器检测目标物,利用单片机MSP410F169的AD采集,将采集到的信号进行滤波,利用PID算法,以及单片机MSP410F169的时钟控制PWM波的占空比来调节电机的转速。通过两个电机来实现跟踪装置的空间旋转跟踪目标物。In order to accomplishing target tracking in photoelectric way, the four-quadrant detector is used to detect ob- jects. Filtering of the signal collected by AD acquisition of single-chip microcomputer MSP410F169 is conducted. The speed of motor is adjusted with PID algorithm and duty ratio of PWM wave produced by MSP410F169. Through two motors, the space ro- tation of the tracking device is realized to track targets.
