摘要:

如何实现通信和控制一体化是当前卫星通信领域的一个崭新研究课题,针对存在干扰的场景,在仅已知非完美信道状态信息的条件下,提出一种鲁棒波束成形算法,保障卫星系统控制稳定性的同时降低系统的能耗。首先,在配置阵列天线的低轨卫星同时接收控制信号和干扰的场景下,建立以信关站发射功率最小化为目标函数、卫星控制稳定性和卫星所受最大干扰满足要求为约束的优化问题。针对该非凸问题,借助李雅普诺夫稳定性定理重构控制稳定性约束,并进一步提出伯恩斯坦不等式和连续凸逼近相结合的鲁棒波束成形算法,求得最优功率分配系数和波束成形权矢量。最后,仿真结果表明所提算法可以在更低功耗下实现优于现有算法的控制性能,有助于提高星载资源利用效率,为通信与控制协同设计提供可靠的理论参考。

Abstract:

How to achieve integration of communication and control is a novel research topic in the field of satellite communication. A robust beamforming algorithm is proposed for scenarios with interference, under the condition of only known imperfect channel state information, to ensure the control stability of the satellite system while reducing the energy consumption of the system. Firstly, in the scenario where a low-Earth orbit satellite with an array antenna simultaneously receives control signals and interference, an optimization problem is established with the minimization of the transmit power of the gateway station as the objective function, and the constraints of satisfying the requirements for satellite control stability and maximum interference experienced by the satellite. For this non-convex problem, the control stability constraint is reconstructed by using the Lyapunov stability theorem, and a robust beamforming algorithm combining Bernstein’s inequality and successive convex approximation is further proposed to obtain the optimal power allocation coefficient and beamforming weight vector. Finally, simulation results show that the proposed algorithm can achieve better control performance than existing algorithms with lower power consumption, which is helpful to improve the utilization efficiency of satellite-borne resources and provides a reliable theoretical reference for the cooperative design of communication and control.
