Abstract :
Analytic expressions for optimal stabilization controllers for constant power loads with LC input filters are derived, directly showing the controller dependence on input filter components as well as operating conditions. The controllers are explicitly designed to stabilize the system with minimum load power modification. The minimization is done both in terms of H2 and H∞ norms, and power reference as well as supply voltage variations is considered. The theoretical results are verified through offline as well as hardware-in-the-loop simulations.
