中文摘要 |
首先提出了一种基于非线性系统相对度的迭代学习控制算法, 并证明了其收敛性. 该算法通过对系统以前的输入和输出跟踪误差信号进行学习来反复调整输入量, 使得系统在经过一定次数的学习以后, 其实际输出趋于期望输出且其内部状态也具有良好的收敛特性. 其次将此算法应用于两轮驱动的移动机器人动力学系统, 数值仿真结果表明了这种算法的有效性. |
英文摘要 |
This paper addresses the learning control problem of nonlinear control systems. Based on the relative degree of nonlinear systems, an iterative learning control algorithm is proposed and the convergence is also proved. The proposed scheme adjusts the control input repeatedly by using the input and output tracking error signal of the previous operation until perfect tracking is achieved. The algorithm is then applied to a two wheel steering nonholonomic mobile robot, and numerical simulations are performed to show its efficiency. |
