The invention relates to the technical field of spacecraft space rendezvous control, and provides a very simple configuration spacecraft and a space rendezvous control method thereof. The spacecraft comprises a laser range finder, a camera, inter-satellite communication equipment and first to sixth thrusters. Through a thruster layout scheme with extremely simple configuration, perfect decoupling of translation and rotation of the star can be ensured. And smooth convergence of each channel of the translation channel can be ensured by adopting a guidance control scheme based on a phase plane. In addition, scheduling control of each thruster is carried out based on a thruster hybrid scheduling algorithm, the translational motion control effect in the rendezvous approaching process of the spacecraft is ensured, and a good tail end docking condition is created. According to the method, free control over three axes and six directions of translation of the spacecraft can be achieved under the condition of extremely simple configuration of the thruster, high control precision can be achieved, on-satellite space and manufacturing and operating cost can be saved, meanwhile, single faults of the thruster can be handled, and the method has a higher practical value.

    本发明涉及航天器空间交会控制技术领域,提出一种极简配置航天器及其空间交会控制方法。该航天器包括激光测距仪、相机、星间通信设备以及第一至第六推力器。本发明通过极简配置的推力器布局方案,可以保证星体平动与转动的完美解耦。并且采用了基于相平面的制导控制方案可以保证平动通道的各通道的顺利收敛。另外基于推力器混合调度算法进行各推力器的调度控制,保证了航天器交会逼近过程中的平动控制效果,创造良好的末端对接条件。本发明能够在推力器极简配置情况下实现航天器平动三轴六向的自由控制,并能达到较高的控制精度,在能够节省星上空间和制造、运行成本的同时还能够应对推力器的单重故障,具有较高的实用价值。
