Abstract:In this paper, we propose a new adaptive control law with Q-parametrization for discrete multi-input multi-output systems subjected to sinusoidal disturbances with time-varying frequency. The rejection of sinusoidal disturbances with known frequency is obtained using partial state reference model control with Youla-Kucera parametrization. However, the frequency of these disturbances can be unknown and/or varying in time. The proposed solution is to estimate on-line the frequency of disturbances and then to adj… Show more
