众所周知，对于线性不确定系统，静态输出反馈滑模控制器只能在与滑模中的降阶动态相关联的特定三元组是可镇定的情况下确定。本文表明，静态输出反馈滑模控制设计问题可以解决更广泛的一类系统，如果一个已知的延迟项故意引入到切换函数。有效地降低阶滑模动态稳定通过引入这种人工延迟。
It is well known that for linear, uncertain systems, a static output feedback sliding mode controller can only be determined if a particular triple associated with the reduced order dynamics in the sliding mode is stabilizable. This paper shows that the static output feedback sliding mode control design problem can be solved for a broader class of systems if a known delay term is deliberately introduced into the switching function. Effectively the reduced order sliding mode dynamics are stabilized by the introduction of this artificial delay.
