采用四象限探测器的双轴跟踪控制技术

采用四象限探测器作为位置传感器，设计出以DSP作为控制器的双轴跟踪控制试验演示系统。通过误差数据采样、计算和比较，在反馈作用下对误差修正，以快速扫描系统和大范围扫描系统构成的双轴联合机构实现运动目标的捕获跟踪。试验结果表明，该系统能够快速捕获并平稳跟踪合作目标，且调试方便，可靠性好，为下一步工程化奠定了基础。

Double-Axis Tracking Control Techniques Based on Four-Quadrant Detector

A demonstration system with DSP as controller used for testing double-axis tracking control techniques is designed by using four-quadrant detector as position sensor. Through error data sampling, calculating and comparing, error correction implemented by feedback, acquisition and tracking of mobile targets are carried out by a double-axis mechanism consisting of a fast scanning system and a large area scanning system. The testing results show that the system can quickly capture and stably track the cooperative targets. Its adjustment is convenient and reliable, thus lays a basis for producing this kind of prototype.
