摘要: 针对一类单控制滞后的非线性时滞系统,利用非线性状态变换的方法进行非线性变 换,得到一线性时滞系统模型;然后利用一带控制记忆的积分变换进行精确无滞后化变换,得 到一无滞后的线性能控标准型系统,从而利用分步设计的思想.实现非线性时滞系统的稳定 化控制.一数值例子的仿真研究说明了该方法的有效性.Abstract: This paper addresses a stabilizing controller design approach for a class of nonlinear time-delay systems based on staged transformation and design technique. For a single-input nonlinear time-delay system, a linear time-delay model is obtained by a nonlinear stage transformation, a delay-free transformation is then introduced to transform the linear time-delay model into a linear controllable system without delay. The stabilizing controller to the primitive nonlinear time-delay system is derived via a staged design method. Simulation result of an example shows that this approach is quite effective.
