Abstract

A methodology to solve the trajectory tracking problem for systems with a noisy position signal is proposed in this paper. Such signal is obtained from a direct measurement, and must be filtered to reduce unwanted noise, and to estimate its time-derivative. It is shown that the use of delay-differential error equations is instrumental to achieve the stability despite a constant delay, which is inherent to the filtering process.
