This paper presents the design and control of a rotary dual-stage actuator (DSA) system, which consists of a voice coil motor (VCM) and a piezoelectric (PZT) microactuator. The performance of the mechanical design is analyzed using a finite element method (FEM) software, whose simulation results are validated experimentally. A nonlinear tracking control is applied to the developed DSA platform for...
This paper presents an optimal track following control design procedure for hard disk drives (HDD) to reach higher track densities given the disturbance and noise model in the HDD and the actuator bandwidth limitation. The linear-quadratic Gaussian/loop-transfer recovery (LQG/LTR) technique is used to design a family of controllers that minimize the position error variance due to disturbance and measurement...
