- 基于史密斯预估器改进控制律,无需复杂积分方法。
- 确保所有状态变量有界,平衡点指数稳定。
- 适合需快速实现的工业控制场景,尤其含延迟的不稳定系统。
本文提出一种针对具有输入延迟的不稳定线性系统的新型控制算法。与现有方法相比,该控制律是对史密斯预估器的改进,实现简单,无需复杂的积分运算。同时,有效解决了闭环系统稳定性问题,保证了所有状态变量的有界性以及平衡点的指数稳定性。
原文摘要 · Abstract (English)
The paper presents a new control algorithm for unstable linear systems with input delay. In comparison with known analogues, the control law has been designed, which is a modification of the Smith predictor, and is the simplest one to implement without requiring complex integration methods. At the same time, the problem of stabilization of a closed system is effectively solved, ensuring the boundedness of all state variables and the exponential stability of the equilibrium point.
