Abstract

In the magnetic disk drives, the Initial Value Compensation (IVC) method at mode switching for head positioning servo is effective in improving the zero-input responses. This note presents a new IVC method which cancels the unfavorable poles of the closed loop by zeros, while minimizing a linear quadratic function of state variables.
