| 摘 要： | 该文提出了一种基于光电传感器的追踪系统控制策略改进方法。以视日追踪系统为例，使用新的三象限位置传感器替代原有四象限传感器测向，降低了系统成本及控制难度。利用差分效果将需采集的模拟量减少到两个，分别对应水平和俯仰两个维度的控制，相比原有的控制策略，控制逻辑更为简单，实时性和可靠性也可以保证。测试表明，该系统能实现在全空域范围内的点光源跟踪，可替代现有四象限视日追踪系统。通过更换末端传感器，此改进的控制策略还可用于空间中电磁波源的追踪，无论在军事领域还是民用领域均有极大的应用价值。

| Abstract: | This paper presents an improved control strategy for tracking system based on photoelectric sensors. Taking the sun-tracking system as an example, the new three-quadrant position sensor is used to replace the original four-quadrant sensor for finding directions, which reduces the system cost and difficulties of controlling. The improved system control strategy uses the differential effect to reduce the analog quantities to two, corresponding respectively to the two-dimension control of the horizontal and vertical directions. Compared with the original control strategy, the proposed control logic is simpler, thus the real time and reliability can also be guaranteed. Tests explain that the system can realize the tracking of the point light source in the whole airspace and replace the existing four-quadrant sun-tracking system. By replacing the terminal sensor, the improved control strategy can also be used to track electromagnetic wave sources in space, which has great application value in both military and civil fields. |
