本文提出了一种新的连续自适应HOSM控制算法。自适应方案的主要优点是它不需要了解匹配不确定性的界限，并且自适应方案不会保守地高估增益本身——这有助于减轻抖动问题。与早期的工作相比，允许调整两个可变参数，这有利于更好的自调节能力和改进的闭环性能。
This paper proposes a new Continuous Adaptive HOSM control algorithm. The key advantage of the adaption scheme is that it does not require knowledge of the bounds on the matched uncertainty, and the gains themselves are not conservatively overestimated by the adaption scheme – which helps mitigate the problem of chattering. Compared with earlier work, two variable parameters are allowed to adapt and this facilitates much better self-tuning capabilities and improved closed-loop performance.
