Magnetic-head positioning control system in HDDs

This file contains a simulator for the benchmark problem of a magnetic-head positioning control system in HDDs.

Setting

1. Download the file.
2. Unzip the file.
3. Start MATLAB.
4. Set the Current Folder as the unzipped folder.

Usage

1. Save the designed controller as Data_Cd.mat and Data_Fm.mat. As an example, the unzipped folder includes these files, which are designed based on the following reference paper. T. Atsumi and S. Yabui, “Quadruple-Stage Actuator System for Magnetic-Head Positioning System in HDDs”, The IEEE Transactions on Industrial Electronics, Vol. 67, No. 11, pp. 9184-9194, (2020-11), DOI: 10.1109/TIE.2019.2955432
2. Execute “Simulation_trackfollow”, which shows the simulation results of the control system.
3. Execute “Plot_control_system”, which shows the frequency responses of the control system.
