A high-performance angular speed measurement method based on adaptive hysteresis switching techniques
A new adaptive angular speed (AS) estimate method minimizes AS errors. Hysteresis switching technology is applied to avoid speed fluctuations. Errors caused by the mechanical errors of optical encoder are removed. Merits of high accuracy, fast response, and less fluctuation are achieved. Two-layer hysteresis switches system is realized in DSC.
