本发明公开了一种分布式无模型预设时间预设性能姿态跟踪控制方法,首先建立刚性航天器姿态模型;其次定义分布式通信方案;最后预设时间预设性能控制:首先建立预设时间预设性能函数,然后建立预设性能约束,最后建立预设性能转换函数。在本发明所设计的分布式控制方案下,每个航天器仅需获取相邻航天器的姿态信息,充分减小了通信负担;本发明控制方案是一种无模型的控制方案,无需设计补偿机制来应对姿态系统的模型不确定性。预设时间预设性能方案不仅可以保证系统暂态性能和稳态性能,而且保证系统到达稳态时间可控。

    The invention discloses a distributed model-free attitude tracking control method with preset time and preset performance. The method comprises the following steps: firstly, establishing a rigid spacecraft attitude model; secondly, defining a distributed communication scheme; and finally, preset time preset performance control: firstly establishing a preset time preset performance function, then establishing a preset performance constraint, and finally establishing a preset performance conversion function. According to the distributed control scheme designed by the invention, each spacecraft only needs to acquire attitude information of adjacent spacecrafts, so that the communication burden is fully reduced; the control scheme is a model-free control scheme, and a compensation mechanism does not need to be designed to cope with the model uncertainty of the attitude system. The preset time and preset performance scheme not only can ensure the transient performance and the steady-state performance of the system, but also can ensure that the steady-state reaching time of the system is controllable.
