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
Fakulti Kejuruteraan Elektrik Say, we need to obtain Bode plot of this TF: Which can be constructed using SIMULINK blocks:
Fakulti Kejuruteraan Elektrik We can to put dummy blocks so that we can define the input-output points
Fakulti Kejuruteraan Elektrik Right click the input point and select Linearization Points Input Point
Fakulti Kejuruteraan Elektrik Right click the output point and select Linearization Points Output Point
Fakulti Kejuruteraan Elektrik Start the Linear Analysis: Tools Control Design Linear Analysis
Fakulti Kejuruteraan Elektrik Start the Linear Analysis: Tools Control Design Linear Analysis
Fakulti Kejuruteraan Elektrik Select the Bode response plot and Linearize Model
Fakulti Kejuruteraan Elektrik Select the Bode response plot and Linearize Model
Fakulti Kejuruteraan Elektrik Try to place input point at several different input points. For each points, obtain the Bode plot
Fakulti Kejuruteraan Elektrik The Bode plots of the 3 different input points:
Fakulti Kejuruteraan Elektrik Open-loop and close-loop plots Crossover frequency approximates close–loop bandwidth
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
