Title :
A frequency selective adaptive controller

Abstract :
It has been established that currently available adaptive control algorithms may become unstable in the presence of high frequency unmodeled dynamics and additive sinuosidal disturbances [1]-[3]. It is argued here that these problems can be overcome by using a controller which is adaptive for some frequency range but fixed for another frequency range which includes high frequencies. One candidate for such a frequency selective adaptive controller is presented and tested by simulation.
