Output feedback sliding mode control based on adaptive sliding mode disturbance observer

open access: yesMeasurement + Control, 2022
In this paper, an adaptive sliding mode disturbance observer is designed to counteract the disturbance actively. By designing the adaptive laws, the assumptions on the disturbance are relaxed in the proposed observer, its first derivative upper bound is ...

Discrete-time output feedback sliding-mode control design for uncertain systems using linear matrix inequalities [PDF]

open access: yes, 2011
An output feedback-based sliding-mode control design methodology for discrete-time systems is considered in this article. In previous work, it has been shown that by identifying a minimal set of current and past outputs, an augmented system can be ...

Design of Sliding Mode Autopilot with Steady-state Error Elimination for Autonomous Underwater Vehicles [PDF]

open access: yes, 2006
Autonomous Underwater Vehicles (AUVs) have nonlinear and time-varying behaviour and unmodelled dynamics. This paper describes the design, development and evaluation of nonlinear sliding mode autopilot system for an AUV to control the speed, steering and ...

Vibration Reduction of the Nonlinearly Tufted Carpet Yarn by a Modified Sliding Mode Control Method

open access: yesShock and Vibration, 2019
The yarn vibration causes the yarn tension value to fluctuate, causing a change in the amount of yarn feed, thus causing a deviation of the carpet pile height from the predetermined value. To solve this problem, the sliding mode control algorithm is used

Sliding Mode Control of Servo Feed System Based on Fuzzy Reaching Law

open access: yesApplied Sciences, 2023
An adaptive sliding mode control method based on the fuzzy exponential convergence law is proposed to solve the jitter problem caused by the sliding mode control of the servo-feed system and to improve the tracking performance of the system.

Total-Amount Synchronous Control Based on Terminal Sliding-Mode Control

open access: yesIEEE Access, 2017
This paper presents a total-amount synchronous control (TASC) strategy for nonlinear systems with uncertainty based on finite-time control theory. In combination with a new type of terminal sliding-mode control strategy, finite-time convergence of TASC ...

Hybrid fuzzy and sliding-mode control for motorised tether spin-up when coupled with axial vibration [PDF]

open access: yes, 2009
A hybrid fuzzy sliding mode controller is applied to the control of motorised tether spin-up coupled with an axial oscillation phenomenon. A six degree of freedom dynamic model of a motorised momentum exchange tether is used as a basis for interplanetary

High-order sliding mode control of a DC motor drive via a switched controlled multi-cellular converter [PDF]

open access: yes, 2011
In this article, we present a high-order sliding mode controller of a DC motor drive connected to a multi-cellular converter. More specifically, we design a second-order (super-twisting) control algorithm for the speed regulation of a DC motor. For this,

Quadcopter Robust Adaptive Second Order Sliding Mode Control Based on PID Sliding Surface

open access: yesIEEE Access, 2018
We present a robust adaptive second-order sliding mode controller that rejects external disturbances and uncertainties to improve the tracking performance of attitude and altitude in a quadcopter based on a Proportional–Integral–Derivative ...

Smooth super-twisting sliding mode control for the class of underactuated systems. [PDF]

open access: yesPLoS ONE, 2018
In this article, Smooth Super-twisting Sliding Mode Control (SSTWSMC) is investigated for the class of underactuated system. In underactuated systems, the control design is not directly applicable as for other systems (known as fully actuated systems ...
