In many tracking control problems, pre‐specified bounds for the evolution of the tracking error should be met. The ‘funnel controller’ addresses this requirement and guarantees transient performance for a fairly large class of systems. In addition, only structural assumptions on the underlying system are made; the exact knowledge of the system parameters is not required. This is in contrast to most classical controllers where only asymptotic behaviour can be guaranteed and the system parameters must be known or estimated. Until now, the funnel controller was only studied theoretically. We will present the results of an analogue implementation of the funnel controller. The results show that the funnel controller works well in reality, i.e. it guarantees the pre‐specified error bounds. The implementation is an analogue circuit composed of standard devices and is therefore suitable for a broad range of applications. (© 2006 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
