作为空间操控的重要手段, 空间遥操作将趋向于更精细和更灵活. 然而传统的空间遥操作控制方法难以兼 顾操作的精细性和灵活性. 针对这一问题, 本文阐述了一种面向自由飞行空间机器人的遥操作分数阶PID控制方法. 首先根据自由飞行空间机器人的动力学模型, 设计了空间遥操作分数阶PID控制系统. 其次, 针对空间遥操作时滞 系统和系统的鲁棒性和抗干扰性要求, 基于系统的参数稳定域, 对分数阶PID控制器的参数进行整定. 最后, 数值仿 真和地面遥操作实验验证了分数阶PID控制器的跟踪性能、抗干扰性、鲁棒性和抗时延抖动性能. 因此, 本文设计的 分数阶PID控制器不仅适合于空间遥操作复杂时滞系统, 而且可以满足未来空间遥操作任务的发展需求.
As one of the most important ways of executing tasks of space operations, space teleoperation will develop to be “more careful and more flexible” in the future. However, the conventional control method for space teleoperation has difficulty in balancing the precision and flexibility of operations. Aiming at this problem, this paper presents a fractionalorder PID (FOPID) control method for teleoperation of a free-flying space robot. First, based on the dynamic model of the free-flying space robot, the FOPID control system for space teleoperation is designed. Then, directing to the space teleoperation time-delay system and the requirements of the robustness and anti-interference capabilities for space teleoperation, the parameters of FOPID controller are tuned based on its stability domain. Finally, numerical simulation and ground teleoperation experiment verifies the tracking performance, anti-interference capabilities and robustness of the FOPID controller. Thus, the FOPID controller designed in this paper is fit for space teleoperation time-delay system and meets the development direction of future space operation tasks.
