本文提出了一个简单的抗饱和方案，线性系统是渐近稳定的，但其输入是有限的速度。证明了具有这些速率限制和抗饱和补偿的闭环系统是全局渐近稳定和局部指数稳定的。此外，L2增益的映射，这是中央的非线性闭环系统的性能被证明是有限的，提供一定的条件得到满足。该方案的一个显著特点是它非常简单，本质上可以被认为是一种改进的IMC抗饱和方案。
This paper proposes a simple anti-windup scheme for linear systems which are asymptotically stable but which have inputs which are limited in rate. The closed-loop system with these rate-limits and anti-windup compensation is proved to be globally asymptotically stable and locally exponentially stable. Furthermore, the L2 gain of a map which is central to the performance of the nonlinear closed-loop system is shown to be finite provided certain conditions are satisfied. One of the notable features of the proposed scheme is that it is exceptionally simple, and can be thought of as, in essence, a modified IMC anti-windup scheme.
