  1. USING LINEAR ANALYSIS IN MATLAB FOR MEP 1422/1522 (MATLAB V7, R14) Dr. Nik Rumzi Nik Idris Dept. of Energy Conversion Fakulti Kejuruteraan Elektrik Universiti Teknologi Malaysia

  2. Fakulti Kejuruteraan Elektrik Say, we need to obtain Bode plot of this TF: Which can be constructed using SIMULINK blocks:

  3. Fakulti Kejuruteraan Elektrik We can to put dummy blocks so that we can define the input-output points

  4. Fakulti Kejuruteraan Elektrik Right click the input point and select Linearization Points  Input Point

  5. Fakulti Kejuruteraan Elektrik Right click the output point and select Linearization Points  Output Point

  6. Fakulti Kejuruteraan Elektrik Start the Linear Analysis: Tools  Control Design  Linear Analysis

  7. Fakulti Kejuruteraan Elektrik Start the Linear Analysis: Tools  Control Design  Linear Analysis

  8. Fakulti Kejuruteraan Elektrik Select the Bode response plot and Linearize Model

  9. Fakulti Kejuruteraan Elektrik Select the Bode response plot and Linearize Model

  10. Fakulti Kejuruteraan Elektrik Try to place input point at several different input points. For each points, obtain the Bode plot

  11. Fakulti Kejuruteraan Elektrik The Bode plots of the 3 different input points:

  12. Fakulti Kejuruteraan Elektrik Open-loop and close-loop plots Crossover frequency approximates close–loop bandwidth

  13. Fakulti Kejuruteraan Elektrik PI controller Transfer function • Contain a zero and a pole at origin • DC gain can be adjusted independently from location of zero

  14. Fakulti Kejuruteraan Elektrik PI controller
