- Description
- We propose a two-degree-of-freedom washout control structure for tracking of sinusoidal references in lightly damped structures subject to sensor drift and measurement noise. An algorithm is derived, assigning stable parameter intervals to a second-order washout damping compensator for a resonant plant with a single dominant mode. Simulation results demonstrate quality drift and noise rejection performance of the proposed method, when tracking a 3 kHz sinusoidal reference in a nanopositioning stage with a 4.5 kHz resonance frequency. Experiments are conducted, validating high efficacy of the proposed washout tracking control strategy.
