| Abstract: | In this paper, a model for read/write head is presented at first, i. e. , the standard state space system of observability, and then, the continuous-time state-space is converted to discrete time G(z) by means of Tustin method. According to the orientation of the locus of the roots, a phase lead digital controller with some zeros is introduced. Finally , a numerical example is given to show the robustness of this design with MATLAB. |
