针对一类带有不确定性的单输入单输出的时滞非线性系统,提出了一种鲁棒非线性控制算法.利用反步设计的迭代设计思想,在每一步构造李亚普诺夫-克拉索夫斯基函数,用放大不等式的方法获得控制器,保证闭环系统的稳定性.以连续搅拌化学反应器为例的仿真结果也验证了控制器具有良好的控制特性. A robust nonlinear control algorithm is proposed for a class of uncertain nonlinear input-output single-output systems with nonlinearity. By using the iterative design concept of backstepping design, Lyapunov- Fusky function, the controller is enlarged by the inequality method to ensure the stability of the closed-loop system.The simulation results using a continuous stirred chemical reactor also verify that the controller has good control characteristics.
