| 摘 要： | 针对带有扰动的一类离散非线性系统的鲁棒迭代学习控制问题, 设计一种基于参数优化的迭代学习控制算法. 该算法能够保证在有初始状态误差和状态、输出扰动的情况下使闭环系统具有鲁棒BIBO 稳定性, 系统输出能够单调收敛于给定输出轨迹的邻域内; 在没有初始状态误差和扰动的情况下能够以零稳态误差跟踪给定输出轨迹. 最后通过仿真分析验证了所提出算法的有效性. |

| Abstract: | A robust parameter-optimal iterative learning control algorithm is presented for a class of discrete time nonlinear dynamic system with disturbances. The proposed algorithm has the property of robust BIBO stability of closed loop system, and the system output can monotonously converge to the neighbor domain of desired trajectories in the presence of state, output disturbances and initial uncertainties. In the absence of these disturbances, the system output can converge to desired trajectories with zero steady-state error. Finally, simulation analysis illustrates the effectiveness of the proposed algorithm. |
