High-order sliding-mode (HOSM) control is called quasi-continuous (QC), if it remains continuous everywhere except the HOSM set, where the sliding variables and their derivatives vanish. Such sliding-mode (SM) control features less chattering. Homogeneous QC SM control is designed for the general uncertain multi-input multi-output case and provides any predefined control smoothness level outside of the HOSM set.

准连续 MIMO 滑模控制


高阶滑模 (HOSM) 控制称为准连续 (QC)，如果它在除 HOSM 集之外的各处保持连续，其中滑动变量及其导数消失。这种滑模（SM）控制的特点是抖动较少。齐次 QC SM 控制专为一般不确定的多输入多输出情况而设计，并提供 HOSM 集之外的任何预定义控制平滑度级别。
