Backstepping with bounded feedbacks [PDF]

Systems and Control Letters, 2004
An extension of the backstepping approach is proposed. It allows to globally asymptotically stabilize by bounded feedbacks families of nonlinear control systems. Explicit expressions of control laws and Lyapunov functions are given.

Command Filtered Adaptive Backstepping

IEEE Transactions on Control Systems Technology, 2012
Implementation of adaptive backstepping controllers requires analytic calculation of the partial derivatives of certain stabilizing functions. It is well documented that, as the order of a nonlinear system increases, analytic calculation of these derivatives becomes prohibitive.

Backstepping for nonsmooth systems [PDF]

Automatica, 2003
The paper presents a smooth version of the backstepping stabilization method. More precisely, the authors consider the system \[ \begin{cases} \dot\eta= f(\eta)+ g(\eta)\xi\\\;\xi=u \end{cases} \] under the assumption that the first subsystem is stabilized by a possibly discontinuous feedback \(\xi=\varphi (\eta)\) (the solutions of the closed-loop ...

Adaptive Backstepping Design of a Microgyroscope [PDF]

Micromachines, 2018
This paper presents a novel algorithm for the design and analysis of an adaptive backstepping controller (ABC) for a microgyroscope. Firstly, Lagrange–Maxwell electromechanical equations are established to derive the dynamic model of a z-axis microgyroscope.

Kinesin backsteps

Biochemical Society Transactions, 2012
Kinesin-1 is a walking machine that takes ~8 nm steps along microtubules. Some aspects of the molecular mechanism of walking are now clear, but many are not. In the present paper, we discuss currently controversial points, focusing on the pathways by which kinesin takes occasional backsteps.

Command filtered backstepping

2008 American Control Conference, 2008
Implementation of backstepping becomes increasingly complex as the order of the system increases. This increasing complexity is mainly driven by the need to compute command derivatives at each step of the design, with the ultimate step requiring derivatives of the same order as the plant.

Backstepping and adaptive backstepping control on robotic ARM

2015 International Conference on Control Communication & Computing India (ICCC), 2015
Robotic arm is extensively used in applications that requires high precision and accuracy such as biomedical and laser treatments. Backstepping and adaptive backstepping are implemented on the system. In this paper, the parameters of the robotic arm are assumed to be initially unknown.
