本文提出了一种新的非线性控制器，适用于有界干扰下的单输入线性系统。控制器提供满足指定幅度和变化率限制的控制信号。该特征通过其包含集值函数的滑动模式结构来实现。该控制器还采用了一个依赖于状态的参数，以扩大吸引区域和收缩终端吸引子。此外，本文提供了一个离散时间实现的建议控制器的基础上，基于模型的隐式离散化计划。数值算例验证了所提控制器的有效性。
This paper proposes a new nonlinear controller applicable to single‐input linear systems under bounded disturbance. The controller provides control signals satisfying specified amplitude and rate‐of‐change limitations. This feature is realized by its sliding mode‐like structure comprising a set‐valued function. The controller also employs a state‐dependent parameter to broaden the region of attraction and to shrink the terminal attractor. In addition, this paper provides a discrete‐time implementation of the proposed controller based on a model‐based implicit discretization scheme. Numerical examples show the validity of the proposed controller.
