Kinesin's backsteps under mechanical load [PDF]

open access: yesPhysical Chemistry Chemical Physics, 2009
Kinesins move processively toward the plus end of microtubules by hydrolyzing ATP for each step. From an enzymatic perspective, the mechanism of mechanical motion coupled to the nucleotide chemistry is often well explained using a single-loop cyclic ...

Relaxed and Hybridized Backstepping [PDF]

open access: yesIEEE Transactions on Automatic Control, 2013
In the present work, we consider nonlinear control systems for which there exist structural obstacles to the design of classical continuous backstepping feedback laws. We conceive feedback laws such that the origin of the closed-loop system is not globally asymptotically stable but a suitable attractor (strictly containing the origin) is practically ...

Backstepping Mechanism of Kinesin-1 [PDF]

open access: yesBiophysical Journal, 2019
Abstract Kinesin-1 is an ATP-driven molecular motor that transports cellular cargo along microtubules. At low loads, kinesin-1 almost always steps forwards, towards microtubule plus ends, but at higher loads, it can also step backwards. Backsteps are usually 8 nm, but can be larger.

Backstepping with bounded feedbacks [PDF]

open access: yesSystems & 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.

Backstepping control of a rigid body [PDF]

open access: yesProceedings of the 41st IEEE Conference on Decision and Control, 2002., 2004
A method for backstepping control of rigid body motion is proposed. The control variables are torques and the force along the axis of motion. The proposed control law and Lyapunov function guarantee asymptotic stability from all initial values except one singular point.

Adaptive Control With Unknown System Dynamics Estimator for Quadrotor Attitude Tracking

open access: yesIEEE Access, 2022
This paper presents an adaptive control scheme via combining with an unknown system dynamics estimator (USDE) for attitude control of quadrotors subject to both parametric uncertainties and external disturbances.

Improved Adaptive Backstepping Sliding Mode Control of Static Var Compensator

open access: yesEnergies, 2018
The stability of a single machine infinite bus system with a static var compensator is proposed by an improved adaptive backstepping algorithm, which includes error compensation, sliding mode control and a κ -class function.
