摘要: We describe the implementation of optimal controllers for damping motion cantilevers used in magnetic resonance force microscopy. demonstrate that control is achievable and torsional coupling provides an effective actuation method. Cantilever Brownian vibrational amplitude was reduced from 2 to 0.16 A resonant quality 2000 5. Applied fields were sufficiently small they would not affect phenomena.
