Chattering suppression methods in sliding mode control systems
Hoon Lee,Vadim I. Utkin +1 more
TL;DR: Analysis of chattering in such systems with unmodeled based on the Lyapunov theory and the describing function method and various approaches to reduce chattering are described including methods based on relay control gain adaptation.
Journal ArticleDOI
Chattering problem in sliding mode control systems
Vadim I. Utkin,Hoon Lee +1 more
TL;DR: The chattering can be caused by fast dynamics which were neglected in the ideal model, and these `unmodeled' dynamics with small time constants are usually disregarded in models of servomechanisms, sensors and data processors.
Proceedings ArticleDOI
Chattering Problem in Sliding Mode Control Systems
Vadim I. Utkin,Hoon Lee +1 more
TL;DR: In this article, the authors considered the problem of sliding mode control with small time constants of real differentiators, which can lead to oscillations in the vicinity of discontinuity surfaces in the system state space.
Journal ArticleDOI
Chattering reduction using multiphase sliding mode control
TL;DR: A design principle of sliding mode control for a multiphase controller is proposed and provides desired phase shifts between phases with the help of adaptive width for the hysteresis loops in switching elements.
Proceedings ArticleDOI
The Chattering Analysis
Vadim I. Utkin,Hoon Lee +1 more
TL;DR: To reduce the chattering, new sliding mode control design is proposed using the methods of changing switching gain along the system states or the magnitude of equivalent control.
