Trajectory Control of Convergent Networks

Neural Processing Letters, 1998
We present a class of feedback control functions which increase the convergence rates of nonlinear dynamical systems. A simple sign function is used to obtain convergence in finite time. We describe a trajectory learning procedure which preserves the convergence property of the system.

Controllability Along a Trajectory: A Variational Approach

SIAM Journal on Control and Optimization, 1993
``The aim of this paper is to give high-order conditions for a point of a reference trajectory to be interior to the reachable set. This property is linked to the minimum-time problem by the fact that if \(\widehat x\) is an optimal trajectory on \([0,T]\), then, for each \(t\in [0,T]\), \(\widehat x(t)\) belongs to the boundary of \(R(\xi_ 0,t)\), i.e.

Directional Control of Bifurcation into Targeted Trajectory

International Journal of Bifurcation and Chaos, 2015
The field of bifurcation control includes several classes of problems that are actively studied with various motivations and from different points of view. The different statements of the problem are articulated by defining various objectives of applying control to the system, depending on the motivation and the specific problem.

On the trajectories of controlled evolution inclusions

Commentarii mathematici Universitatis Sancti Pauli = Rikkyo Daigaku sugaku zasshi, 1990
The author studies a nonlinear controlled evolution inclusion with control constraints. The existence of optimal admissible pairs is established. Then the weak continuity of the solution is proved with respect to the control function. For linear problems the case of controlled coefficients is studied by means of the concept of \(G\)- convergence.

Predictive Controller Issues for Trajectory Control

SAE Technical Paper Series, 1983
<div class="htmlview paragraph">An advanced trajectory control system is defined for operation in the 1990's. Basic functions of trajectory control are the selection and control of the aircraft trajectory. For the 1990's, the system needs to operate on all available knowledge of the mission and environment.

Optimization control for biped motion trajectory

2014 International Conference on Audio, Language and Image Processing, 2014
Character animation is important in many applications, such as video games, movie production, and somatosensory interaction. However, it is difficult to control the locomotion of a virtual character in a dynamic environment, because bipeds are under-actuated and unstable.

Swing Trajectory Control for Large Excavators

2010
There is a strong push within the mining sector to automate equipment such as large excavators. A challenging problem is the control of motion on high inertia degrees of freedom where the actuators are constrained in the power they can deliver to and extract from the system and the machine’s underlying control system sits between the automation system ...

Trajectory tracking control of an underactuated capsubot

Autonomous Robots, 2015
Trajectory tracking control of underactuated systems is one of the challenging issues. This paper proposes a two-stage control strategy for the trajectory tracking of a class of underactuated mechanical systems. Two new acceleration profiles for the capsubot motion generation are proposed for the motion control of the capsubot. The optimum selection of

Graded approximations and controllability along a trajectory

Proceedings of the 28th IEEE Conference on Decision and Control, 1990
Graded approximations of an affine control system are defined and their properties are investigated. In particular, it is proved that the local controllability along a reference trajectory of an approximating system implies the local controllability along the corresponding reference trajectory of the original system.Using graded approximations ...
