TI’s Compensation Designer provides an easy GUI interface, to calculate the coefficients that are needed to be programmed onto the micro-controller to implement a compensator as part of a closed loop system. The GUI lets the user select different compensator styles like PID, Two Pole Two Zero, and so forth, and allows the user to save up to five compensator values.
The GUI displays the Plant, the Open Loop and the Compensator Frequency Response. The Pole and Zeroes of the compensator, are marked on the Open Loop Curve on the GUI using a cross and circle, respectively. Critical values such as open loop gain crossover frequency (Folg_cf), Phase Margin and Gain Margin are displayed on the GUI at the bottom, and a label showing “Stable Loop” and “UnStable Loop” is displayed if the system has healthy Bandwidth, Phase Margin and Gain Margin.
For Plant frequency response, depending upon where the Compensation Designer is invoked from, the user can select to use the mathematical model of the power stage or the experimental data gathered using SFRA, to design the compensator.
