| 摘 要： | 针对一类存在不确定性或者输入扰动的严参数反馈形式非线性混沌系统,提出一种基于反步法的自适应变结构控制器。结合反步法和变结构控制,在第1步到第n -1步,用递推方法来选取Lyapunov函数,运用自适应反步法设计,在第n步(n阶系统) ,选择适当的滑动面来确定变结构控制器,以实现系统的全局调节或跟踪。仿真结果表明,所提出的控制器对存在输入扰动和参数不确定时具有强鲁棒性

| Abstract: | An adaptive variable structure controller based on backstepping is proposed for a class of strict-feedback nonlinear chaotic systems with uncertain parameters or input distrubance. The proposed control scheme is a combination of the backstepping and the variable structure control by choosing Lyapunov function recursively. At the first step to the n-1 step, adaptive backstepping is used in design and at the nth step (for n-order system), a suitable sliding surface is selected to design a variable structure controller to solve the problem of global regulation and tracking. Simulation results verify the proposed scheme's robustness in the presence of unknown perturbation inputs. |
