A code to compute robust proportional-integral-derivative (PID) and current feedback controller to ensure uninterruptible power supply (UPS) stability and performance, whose gains are tuned by means of regional pole placement with LMIs. Although switching effects are obviously not considered in such linear approximation, the output plotted without a graphical environment facilitates learning and analysis of the resulting controller.
Details: Main file named as 'pid_main.m'. Robustness to load variation guaranteed. Tracking error minimized but NOT ELIMINATED. Since k_d is computed from a linear combination of K, its positive value is not guaranteed.
