Switching-based Sinusoidal Disturbance Rejection for Uncertain Stable Linear Systems
The problem of rejection of sinusoidal disturbances
with known frequencies acting on an unknown singleinput
single-output linear system is addressed in this note.
We present a new approach that does not require knowledge
of the frequency response of the transfer function over the
frequency of interest. The proposed methodology reposes upon
the combination of the classic feedforward control algorithm
and logic-based switching. The use of three different switching
logics is proposed in this paper, namely: pre-routed, dwell-time
and hysteresis switching. A comparative evaluation of the three
switching strategies is performed via a simulation study
