INSTANTANEOUS DARK STATE AND TRAJECTORY TRACKING
International Journal of Quantum Information, 2013State steering and tracking have attracted a lot of interests due to their wide applications. In this paper, we present two concrete examples of trajectory tracking of an open quantum system with time-dependent Lindblad operator which has an eigenstate |ψs(t)〉 with eigenvalue 0. We work out the first case analytically while numerically the second case.

In this chapter we extend the passivity-based method, developed for regulation in the previous chapter, to solve trajectory tracking problems. The first main modification that we have to make is that for tracking, besides reshaping the potential energy of the EL plant, we must also shape the “kinetic energy” function.

Tracking trajectories of the cart-pendulum system
Automatica, 2003The planar inverted pendulum on a cart is one of the most remarkable physical devices. Here, the problem of tracking a periodic trajectory of the cart-pendulum system as a tracking control problem for nonlinear systems is solved by means of a Lyapunov stability technique. One uses mainly the feedforward property.

Trajectory tracking for a particle in elliptical billiards
International Journal of Control, 2008An infinitely rigid unitary mass (particle) is considered, moving on a planar region delimited by a rigid elliptical barrier (elliptical billiards) under the action of proper control forces. A class of periodic trajectories, involving an infinite sequence of non-smooth impacts between the mass and the barrier at fixed times, is found by using an LMIs ...

Tracking Trajectories with a Robotic Manipulator with Singularities
2007This research presents a trajectory control for non-redundant serial-link manipulators that is valid for trajectories with ordinary singularities of codimension one and non-ordinary singularities of any codimension. Firstly, it is presented a unified view of tracking algorithms for trajectories with ordinary singularities.

Stable trajectory tracking for biped robots
Proceedings of the 39th IEEE Conference on Decision and Control (Cat. No.00CH37187), 2002The control of underactuated biped robots in single support phase can be done choosing a certain number of output functions which are dependent on the state variables, i.e. on angular positions and velocities; the choice of these output functions is better if they yield the definition of a minimal phase system. In the paper some examples are discussed.

Fault recovery by nominal trajectory tracking
2008 American Control Conference, 2008Fault accommodation is meant to control the faulty system so as to preserve a given functionality. In model matching, the state dynamics is wished to be fault-invariant, leading to the family of pseudo-inverse and modified pseudo- inverse methods. In this paper, rather than the closeness between the faulty and the nominal system matrices, it is the ...

High-gain MFC for trajectory tracking
at - AutomatisierungstechnikAbstract We consider trajectory tracking for minimum-phase nonlinear systems in Byrnes-Isidori form using the model-following control (MFC) architecture. The tracking problem is motivated by a hierarchical control concept where a higher-level instance provides the reference trajectory at run-time.
