| 摘 要： | 利用神经网络和滑模控制，研究带有饱和输入的一类非线性系统。为了便于问题分析，引入饱和约束模型输出与控制输入的差值这个变量，分5种情况讨论，求得神经网络权值的在线调节律，得到保证闭环系统稳定的控制律。利用Lyapunov函数，证明了闭环系统的稳定性；仿真实验说明了算法的有效性。

| Abstract: | This paper is concerned with a class of SISO nonlinear systems with input saturation,which is studied by sliding mode control and neural networks.A new parameter is introduced as the difference between control input and the output of the input saturation,5 situations are discussed,the weight updating laws of the neural networks are acquired.The control law can stabilize the closed-loop system,the stability of the system is proved by Lyapunov function,the simulation results show the feasibility of this method. |

| Keywords: | nonlinear systems input saturation neural networks sliding mode control |
