针对一类非线性离散系统 ,利用 Lyapunov方法和加权最小二乘估计设计了一种自适应控制器 ,在对非线性 (不加增长条件约束 )的情况下 ,得到了闭环系统的全局跟踪性能 .
For a class of nonlinear discrete systems, an adaptive controller is designed by using Lyapunov method and weighted least squares estimation. The global tracking performance of the closed-loop system is obtained under the condition of non-linearity (without constraint of growth).
