UPS PID Robust Controller Design

Computes proportional-integral-derivative (PID) robust controller and current feedback in order to ensure UPS stability and performance.

A code to compute proportional-integral-derivative (PID) robust controller and current feedback gain in order to ensure uninterruptible power supply (UPS) stability and performance. PID and current gain tunned by means of robust pole placement in LMI regions. Output plotted without the need of graphical environment circuits, which makes it easy for study applications.

Details: Robustness to load variation (inside bounds) guaranteed. Tracking error minimized but NOT ELIMINATED. Consider using a reference-frame transformation or a PMR controller for better response. Main file named as 'pid_main.m'.
