Abstract

A class of nth-order linear systems with a variable structure is discretized and analyzed in detail. The occurrence and structure of pseudo-sliding modes give insight into corresponding sliding modes for the continuous system, and enable the relation between system parameters and the step size to be explored. A discretization can be used which gives a mathematical model revealing details of the chattering along a surface. A sufficient condition on the step size and the system and switching parameters to ensure the existence of a pseudo-sliding mode is derived. The analysis is illustrated with a simulation study of second-order systems.<>
一类离散变结构系统
对一类n阶变结构线性系统进行了离散化分析。伪滑模的出现和结构使我们能够深入了解连续系统的相应滑模,并使我们能够探索系统参数与步长之间的关系。离散化可以给出一个数学模型,揭示沿表面的抖振的细节。给出了系统步长、系统参数和开关参数存在伪滑模的充分条件。通过对二阶系统的仿真研究说明了这一分析。
