title: MEMS applications in computer disk drive dual-stage servo systems
abstract: We present a decoupled discrete time pole placement design method, which can be combined with a self-tuning scheme to compensate variations in the microactuator's (MA's) resonance mode. Section I of the paper describes the design and fabrication of a prototype microactuator with an integrated gimbal structure. Section II presents a decoupled track-following controller design and a self-tuning control scheme to compensate for the MA's resonance mode variations
