提出了抖振的正式数学定义。颤振现象分为三种类型。特别是第一种是无害的，无法避免。颤振特性的各种控制方法被认为是。通过高阶滑模的适当使用，证明了危险的第二类和第三类抖振现象是可以消除的。快速稳定的执行器和传感器只产生第一种类型的抖振HOSM系统，几乎从来没有影响滑动运动。计算机仿真验证了理论结果。
A formal mathematical definition of chattering is proposed. Chattering phenomena are classified into three types. In particular, the first type is harmless and cannot be avoided. Chattering properties of various control approaches are considered. The dangerous second and third types of chattering phenomena are proved to be removable by proper use of high-order sliding-modes (HOSM). Fast stable actuators and sensors only generate the first type of chattering in HOSM systems and practically never affect the sliding motion. Computer simulation confirms the theoretical results.
