An Adaptive SMO Approach for Low-Chattering Sensorless Control of PMSM

IEEE transactions on power electronics
This article presents a sensorless control strategy for permanent magnet synchronous motors (PMSMs) with low chattering based on an adaptive sliding mode observer (SMO).

Chattering-Free Fixed-Time Robust Sliding Mode Controller for Grid-Connected Inverters Under Parameter Variations

IEEE Journal of Emerging and Selected Topics in Power Electronics
This article proposes and experimentally validates a new chattering-free fixed-time robust sliding mode controller for the grid-connected three-phase two-level inverter through an RL filter. The proposed method addresses the reference trajectory tracking

Low-chattering discretization of sliding mode control

IEEE Conference on Decision and Control, 2021
A new chattering-mitigation method is proposed for discontinuous dynamics discretization. Its application to feedback and output-feedback homogeneous sliding-modes significantly diminishes the control chattering in the absence of noises, while preserving

Chattering arcs and chattering controls

Journal of Optimization Theory and Applications, 1973
There are two different meanings of the wordchattering in control theory and optimization theory. Chattering arcs of the first kind are related to the notion of relaxation of the control (i.e., convexization of the maneuverability domain). Some sufficient conditions of equivalence of these notions are defined.

Approximate solutions for chattering control and chattering arc

Acta Astronautica, 2000
Abstract The approximate solution for chattering arc of the first kind chattering control has been studied. Both symmetrical and asymmetrical cases are considered. A practical example analyzed in this paper is the maximum drag reentry flight of a winged space vehicle in the vertical plane. The control variable is the normalized lift coefficient (NLC),

Finite-time cluster synchronization for a class of fuzzy cellular neural networks via non-chattering quantized controllers

Neural Networks, 2019
This paper considers the finite-time cluster synchronization (FTCS) of coupled fuzzy cellular neural networks (FCNNs) with Markovian switching topology, discontinuous activation functions, proportional leakage, and time-varying unbounded delays.

Finite-time synchronization of nonidentical BAM discontinuous fuzzy neural networks with delays and impulsive effects via non-chattering quantized control

Communications in nonlinear science & numerical simulation, 2019
Considering the fact that the effects of both impulse and time delay are difficult to deal with in finite-time control area, this paper investigates finite-time synchronization (FTS) of drive-response BAM fuzzy neural networks (BAMFNNs) with time delays ...
