摘要

已知受寄生动力学扰动的滑模控制系统表现为“真正的”滑模控制。实际的SM具有有限的频率切换(抖振)特征,其平均运动与降阶模型中的运动不同。然而,作为SM系统运动的两个组成部分,抖振和平均运动属于两个不同的频率范围(谱)。因此,某种频率特性形状补偿的目的是达到期望的抖振频率和增强平均运动的动力学成为可能。这一研究是本文的主题

Frequency-domain Design of Compensating Filters for Sliding Mode Control Systems
It is known that a sliding mode (SM) control system perturbed by parasitic dynamics exhibits the "real" SM. The real SM features finite frequency switching (chattering) and the averaged motions being different from those in the reduced-order model. Yet, chattering and the averaged motion - being two components of the motion in the SM system - belong to two different frequency ranges (spectra). As a result, some kind of frequency characteristic shape compensation aimed at achieving the desired frequency of chattering and enhancing the dynamics of the averaged motions becomes possible. This research is the subject of the present paper
