| 中文摘要 |
| 针对控制方向未知的、存在周期性非参数不确定性的一类非线性系统, 给出零误差跟踪的重复控制方法. 引入Nussbaum函数设计自适应重复控制器, 参数估计修正律采用完全饱和形式, 将参数估计囿于预先给定的范围内. 分析表明, 闭环系统中所有信号本身有界, 且跟踪误差本身趋于零. 数值仿真结果验证了算法的有效性. |
| 英文摘要 |
| We present an adaptive repetitive control for a class of nonlinear systems with periodic nonparametric uncertainties and unknown control direction. This repetitive controller is designed with the aid of Nussbaum function; and the saturation mechanism adopted in the learning algorithm confines the estimated parameters to a pre-determined region. The proposed control method guarantees that all the signals in the closed-loop are bounded and the tracking error converges to zero as time approaches infinity. Numerical simulations are carried out to demonstrate the effectiveness of the presented control scheme. |
