ADAPTIVE COMPENSATION OF BIASED SINUSOIDAL DISTURBANCES WITH UNKNOWN FREQUENCY

The problem of designing an output feedback compensator for any biased sinusoidal disturbance is considered. In this paper, we will develop the approach presented in (Marino et al., 2003). In (Marino et al., 2003) a compensator of order (2n+6) is proposed, which solves the posed problem by using the adaptive observers developed in (Marino and Tomei, 1995; Marino et al., 2001). This problem is solved by a (n + 4)-order compensator.
