Process for the design of an optimally against vibration isolated suspension device for a disk drive

摘要

An optimal vibration mount (132) for a disc drive (100) is designed by computing external, XI, and internal, THETA, disturbance models for the disc drive and defining an inertia matrix, M, for the disc drive. A state estimator, such as a Kalman filter, is defined based on the inertia matrix and external and internal disturbance models, and a covariance matrix, SIGMA , is derived based on the filter algebraic Riccati equation. The state estimator gain, H, is calculated from SIGMA (I0)' THETA -1, and the optimal mount damping, B, and stiffness, K, parameters are derived from the state estimator gain and inertia matrix, H=(a).
