利用单位分解在紧致域上能够以任意给定精度逼近连续函数的性质,针对一类不确定非线性系统设计了带有PI结构的自适应跟踪控制器.结果表明:这种控制器可以使输出跟踪误差渐近收敛到零点的一个小邻域内,并保证闭环系统的所有状态一致有界.最后的仿真实例说明了该方法的有效性.
By using the unit decomposition, the adaptive tracking controller with PI structure can be designed for a class of uncertain nonlinear systems with compactness approximating continuous functions of any given accuracy. The results show that this controller can make The output tracking error converges asymptotically to a small neighborhood of zero and guarantees that all states of the closed-loop system are uniformly bounded. The last simulation example shows the effectiveness of this method.
