Compensating for a Multisinusoidal Disturbance Based on Youla–Kucera Parametrization

International audienceWe consider the problem of compensation for a multisinusoidal disturbance for alinear stationary system with a given nominal control law. We consider the general structureof a controller that lets one use arbitrary algorithms for identification of disturbance parameters satisfying certain assumptions. The proposed structure is based on the Youla–Kuceraparametrization and lets one compensate for a disturbance while preserving nominal behaviorof a control system with respect to the reference
