交会对接仿真实验方案的研究

提出一种地面交会对接仿真实验方案。其中，由ＣＣＤ相机、三轴位置及三轴姿态转台系统模拟追踪器；由三轴转台及五点光源系统模拟目标器。通过ＣＣＤ相机获取目标五点光源的视频信息，并由视频处理机和计算机进行快速处理。追踪能快速算出目标器的位置和姿态，然后通过伺服系统和执行机构准确跟踪目标。建立了交会对接过程的数学模型，通过仿真验证了模型的有效性。

INVESTIGATION OF SIMULATION TESTING PROJECT ON RENDEZVOUS AND DOCKING

This paper presents a simulation testing project on ground rendezvous and docking, which consists of CCD camera, triaxial position servo set and triaxial attitude turn table. The system composed of CCD camera, triaxial position servo set and triaxial attitude turn table imitates the chasing vehicle, while the system composed of triaxial calibration turn table and five point sources imitates the target vehicle. The chasing vehicle obtains target's visual frequency information of five point sources through CCD camera, calculates target's position and attitude angle with the aid of visual frequency processor and computer, and then precisely traces the target by servo system and actuator. The mathematical model of rendezvous and docking procedure is built up. The simulation result proves the effectiveness of the model.
