On the controller form for linear hyperbolic MIMO systems with dynamic boundary conditions
Stefan Ecklebe, Frank Woittennek
This contribution develops an algebraic approach to obtain a controller form for a class of linear hyperbolic MIMO systems, bidirectionally coupled with a linear ODE system at the…
Backstepping-based tracking control of the vertical gradient freeze crystal growth process
Stefan Ecklebe, Nicole Gehring
The vertical gradient freeze crystal growth process is the main technique for the production of high quality compound semiconductors that are vital for today's electronic applicati…
Control of the Vertical Gradient Freeze crystal growth process via backstepping
Stefan Ecklebe, Frank Woittennek, Jan Winkler
This contribution presents a backstepping-based state feedback design for the tracking control of a two-phase Stefan problem which is encountered in the Vertical Gradient Freeze cr…
Towards model based control of the Vertical Gradient Freeze crystal growth process
Stefan Ecklebe, Frank Woittennek, Jan Winkler +2
In this contribution tracking control designs using output feedback are presented for a two-phase Stefan problem arising in the modeling of the Vertical Gradient Freeze process. Th…
