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.

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.

Laminar separating flow over backsteps and cavities. I - Backsteps

AIAA Journal, 1981
Although significant data on flow over backward facing steps and cavities in turbulent flow are available, the corresponding data for the laminar flow are rather scant. The present work reports the results of an experimental investigation carried out at a wind speed of 1.8 m/s over three backward facing steps 0.625,1.25, and 2.5 cm high; the separating

�������������������� �������������� �������������������� ���� ���������� ���������������������� Lyapunov: �� �������������� Backstepping

2020
This thesis presents techniques to design control laws for nonlinear dynamical systems, based on Lyapunov functions. First of all, we introduce some preliminary concepts from the theory of dynamical systems such as the flow and the notion of equilibrium point.

Robust chattering free backstepping/backstepping sliding mode control for quadrotor hovering

2016 IEEE Information Technology, Networking, Electronic and Automation Control Conference, 2016
This paper presents a design method of robust nonlinear controller with inner-outer loop structure (robust chattering free backstepping/backstepping sliding mode controller). Because backstepping control and sliding mode control are in nature two different robust controllers, the combination of them brings up a controller which has stronger robustness ...

Backstepping Boundary ControlA Tutorial

2007 American Control Conference, 2007
After briefly overviewing the application problems that call for boundary control method and the existing techniques for control of PDEs, the paper introduces the key concepts for spatially continuous backstepping control design for PDE systems. After that, a general procedure for parabolic PDEs of a "spatially causal" class is presented, followed by a

Locally optimal backstepping design

Proceedings of the 36th IEEE Conference on Decision and Control, 2002
Using integrator backstepping we present a robust optimal control design method for nonlinear strict-feedback systems with disturbances also in strict-feedback form. We globally stabilize such systems while obtaining local optimality and global inverse optimality.
