Abstract:

In this paper, performance analysis of generalized extended state observer (ESO) in handling fast-varying sinusoidal disturbances is presented. It is shown that the higher order ESO offers improvement in the tracking of fast-varying sinusoidal disturbances, if the ESO bandwidth is chosen significantly larger than the frequency of the disturbance and ensuring that it is sufficiently smaller than unmodeled high frequency dynamics. The frequency and time-domain analysis results are presented, and the findings are verified through numerical simulations and experimentation on Quanser's motion control module.
