The goal of this note is to highlight that the reformulation of saturation as constraints, typical of the computation of the maximal output admissible sets used in the reference governor literature, is not without loss of generality and may introduce a relevant amount of conservativeness. The note also proposes a modified reference governor able to overcome this limitation.

输出容许集和参考调速器：饱和度不是约束！

本说明的目的是强调将饱和度重新表述为约束条件，这是参考调控器文献中使用的最大输出容许集计算的典型特征，并非不失一般性，并且可能会引入相关数量的保守性。该说明还提出了一种能够克服这一限制的修改后的参考调速器。
