Abstract :
In this paper, the problem of tonal disturbance rejection via direct adaptive control is considered. The key problem feature is compared with the usual adaptive tracking problem. Traditional model reference and pole placement approaches are attempted, and their advantages and drawbacks are given. We then propose an adaptive solution based on a new parametrization scheme which is unique to the given problem. Simulation studies are used to compare these different schemes
