中文摘要
      针对非参数不确定时滞系统, 给出能够实现跟踪误差本身沿整个周期完全跟踪的重复控制器设计. 针对系统不确定特性的界函数已知和未知两种情形, 分别分析闭环系统的稳定性与收敛性. 控制器中学习部分采用完全饱和形式, 使得参数估计囿于一预先给定的范围内. 该控制律可保证闭环系统内所有信号有界以及跟踪误差本身趋于零. 数值仿真表明算法的有效性.
英文摘要
      This paper presents a repetitive control design for a class of time-delay systems with non-parametric uncertainties. The global stability of the learning system and the asymptotic convergence of the tracking error are established for cases of both known and unknown bounded functions of system uncertainties, respectively. The estimated parameters are always confined to a pre-defined region by the fully saturated learning algorithms. The repetitive control scheme can guarantee that all the signals in the closed-loop system are bounded and the tracking error will converge to zero as time approaches infinity. The numerical simulation is also carried out to demonstrate the effectiveness of the presented learning scheme.
