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 ...

On Sliding Mode Observers for Systems with Unknown Inputs [PDF]

open access: yes, 2007
International audienceThis paper considers the problem of designing an observer for a linear system subject to unknown inputs. This problem has been extensively studied in the literature with respect to both linear and nonlinear (sliding mode) observers.

Sliding Mode Control for Slosh-Free Motion using a Nonlinear Sliding Surface [PDF]

open access: yes, 2013
A new nonlinear switching surface is proposed for the design of a sliding mode controller for a class of mismatched uncertain systems. A control system for slosh-free motion of a partially filled liquid container is sought.
