We reconsider the singular control problem with marginal stability of the closed loop system, when the transfer matrix from the input to the output can have linearly dependent columns, and zeros on the extended imaginary axis. We present a new theoretical (existence) result and a new numerical algorithm, based on finding an orthogonal transformation of the matrix pencil associated to the Euler-Lagrange...
In this paper, we design boundary feedback controllers at the interior node to stabilize a star-shaped network of Euler-Bernoulli beams. The beams are hinged each other, that is, the displacements of the structure are continuous but the rotations of the beams are not continuous. The well-posed-ness of the closed loop system is proved by the semigroup theory. We show that the system is asymptotically...
The aim of this contribution is a systematic approach of modelling, simulation and control of a parallel robotic manipulator. Regarding the framework of structured analysis of dynamical systems, the mathematical description yields a set of differential equations and some additional holonomic constraints which appear as algebraic relations between single state variables. By defining a number of ficticious...
