In this digest, a digital twin approach for adaptive controller tuning is presented. For an anticipated load profile, step transitions are input into a simulation-based optimizer which utilizes a state-space averaged model to determine optimal control parameters for the future operating point after the next upcoming load step. This process aims to minimize voltage overshoot and settling time. Control parameters are adjusted preemptively before load each step and subsequently validated through a switching model simulation. This guarantees good dynamic performance throughout the load profile. Experimental results are provided for a simple example involving a bidirectional DC/DC converter connected to a pulse load. Compared to the static PI controller, the digital twin-enabled adaptive tuner reduced voltage overshoot by 1.5% and settling time by 3.5%.
