Abstract
The focus of this paper is on the development of time-delay filters to accomplish tracking
of periodic signals with zero phase errors. The class of problems addressed include systems
whose dynamics are characterized by lightly damped modes. A general approach
for the zero-phase tracking of periodic inputs is presented followed by an illustration of
single harmonic tracking of underdamped second-order systems with relative degree two.
A general formulation of the approach is then posed for higher-order systems and systems
including zeros. The paper concludes with the illustration of enforcing constraints
to desensitize the time-delay filter to uncertainties in the location of the poles of the system
and forcing frequencies. A numerical practical design case based on a medical X-ray
system is used to illustrate the potential of the proposed technique.
