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.

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.

Backstepping control of polymerization reactor

2013 9th Asian Control Conference (ASCC), 2013
This paper presents adaptive backstepping methodology for controlling polymerization process under parametric uncertainty and input saturation. In general controlling complex chemical processes is a challenging problem due to the structural mismatch and uncertainty of parameters. Adaptive algorithm, whether linear or non-linear, is an essential tool to

Backstepping Control for a Quadrotor Helicopter

2006 IEEE/RSJ International Conference on Intelligent Robots and Systems, 2006
This paper presents a nonlinear dynamic model for a quadrotor helicopter in a form suited for backstepping control design. Due to the under-actuated property of quadrotor helicopter, the controller can set the helicopter track three Cartesian positions (x, y, z) and the yaw angle to their desired values and stabilize the pitch and roll angles.

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

Modified backstepping control of Quadrotor

International Multi-Conference on Systems, Sygnals & Devices, 2012
In this paper, a modified backstepping approach will be developed and applied to control unmanned areial vehicles (UAVs), Quadrotor. In this modified backstepping approach, the number of control parameters is reduced by half compared with the classical back stepping approach used in the literature.

Command filtered adaptive backstepping

Proceedings of the 2010 American Control Conference, 2010
As the order of the system increases, implementation of adaptive backstepping controllers becomes increasingly complex due to the necessity to calculate analytically the partial derivatives of certain stabilizing functions with respect to the system state.
