In this work, the tracking control problem of nonlinear system which contains unknown parameters, multiple state delays, external disturbances and the dead-zone input is studied. By introducing a dynamic gain-based adaptive control strategy and employing a new Lyapunov–Krasovskii (L–K) functional, we construct an adaptive tracking controller to ensure the boundedness of all the states and guarantee the tracking error small enough. Two examples are given to verify the correctness of the control theory.

具有时滞、外部扰动和死区输入的不确定非线性系统的自适应跟踪控制

在这项工作中，研究了包含未知参数、多状态延迟、外部扰动和死区输入的非线性系统的跟踪控制问题。通过引入基于动态增益的自适应控制策略并采用新的 Lyapunov-Krasovskii (L-K) 泛函，我们构建了一个自适应跟踪控制器，以确保所有状态的有界性并保证跟踪误差足够小。给出两个例子来验证控制理论的正确性。
