To suppress external vibration for a hard disk drive shock sensor feed forward techniques are proposed. To design the feedforward controller phase approximation is important. In this paper a method to design a Finite Response Filter (FIR) type controller with phase constraint is proposed. The result is compared with the method which does not use the phase constraint. For the filter with small order the proposed method can approximate the phase better.
