ABSTRACT:
An optimal vibration mount for a disc drive is designed by computing external, Ξ, and internal, Θ, 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, Σ, is derived based on the filter algebraic Riccati equation. The state estimator gain, H, is calculated from Σ(I 0)′Θ−1, and the optimal mount damping, B. and stiffness, K, parameters are derived from the state estimator gain and inertia matrix,H=(M-1BM-1K).
