- •
Proposes method for mitigating nonlinear friction in nanopositioning stages using dither.
- •
Stage is designed and controlled to eliminate parasitic vibration caused by dither.
- •
Method is model free and robust to changes in friction parameters.
- •
Demonstrates up to 52% reduction in settling time with insignificant heat and wear.
