- Description
- This article compares the performance of three feedback control methodologies for high performance nanopositioning applications. Integral resonance damping control is a new approach for controlling mechanical systems. In this approach, the system resonances are actively damped rather than inverted which maximizes the closed-loop bandwidth and provides robustness to changes in the resonance frequencies. This technique is comprehensively compared to the standard methods of PI and inversion control in a practical environment. A five times improvement in the settling-time and bandwidth is demonstrated.
