  abstract     = {{We extend a recent result in high-gain feedback output tracking control to achieve exact tracking within finite time, i.e., the output of a system and its relevant derivatives have certain exact values at a predefined finite time.
We propose a new funnel control scheme achieving this, whereas the error between the reference and the output evolves within prescribed bounds.
Applications of this are, for instance, linking up two parts of a train, or docking spaceships.}},

  abstract     = {{We study output reference tracking of systems with high relative degree via output feedback only; this is, tracking where the output derivatives are unknown.
To this end, we prove that the conjunction of the funnel pre-compensator with a minimum phase system of arbitrary relative degree yields a system of the same relative degree which is minimum phase as well. 
The error between the original system's output and the pre-compensator's output evolves within a prescribed performance funnel; and moreover, the derivatives of the funnel pre-compensator's output are known explicitly. 
Therefore, output reference tracking with prescribed transient behavior of the tracking error is possible without knowledge of the derivatives of the original system's output; via funnel control schemes for instance.}},

  abstract     = {{<jats:title>Abstract</jats:title><jats:p>We consider tracking control for multibody systems which are modeled using holonomic and non-holonomic constraints. Furthermore, the systems may be underactuated and contain kinematic loops and are thus described by a set of differential-algebraic equations that cannot be reformulated as ordinary differential equations in general. We propose a control strategy which combines a feedforward controller based on the servo-constraints approach with a feedback controller based on a recent funnel control design. As an important tool for both approaches, we present a new procedure to derive the internal dynamics of a multibody system. Furthermore, we present a feasible set of coordinates for the internal dynamics avoiding the effort involved with the computation of the Byrnes–Isidori form. The control design is demonstrated by a simulation for a nonlinear non-minimum phase multi-input, multi-output robotic manipulator with kinematic loop.</jats:p>}},
