摘要
运用Lyapunov稳定性理论和有限时间有界理论,讨论了基于采样数据卫星姿态的有限时间有界(FTB)输出反馈控制问题.首先给出了使闭环系统满足FTB的充分条件,然后将输出反馈控制器的存在问题转化为线性矩阵不等式(LMI)的可行性问题.最后,仿真实验验证了所设计的控制器的有效性和可行性.
By using the Lyapunov theory and finite time boundedness （FTB） theory, an output feedback controller was designed for satellite attitude based on sampled-data measurement. Sufficient conditions are presented to ensure that the closed-loop system is FTB. Then, the existence of the controller can be transformed into the feasibility problem of the linear matrix inequalities（LMIs）. Finally, an example is given to illustrate the validity and effectiveness of the methodology.
