Robust performance enhancement using disturbance observers for hysteresis compensation based on generalized Prandtl-Ishlinskii model
Original language description
This paper presents an approach employing disturbance observers (DOBs) to enhance the performance of inverse-based hysteresis compensation based on the generalized Prandtl-Ishlinskii model in feedback control reference-tracking applications. It is firstshown that the error resulting from inexact hysteresis cancelation is an L-bounded signal. Hence, a DOB is designed to cancel its effect and improve the closed loop robust tracking performance in the presence of plant uncertainty. The design of the DOB makes use of an equivalent internal model-based estimation of exogenous disturbances, where the internal model dynamics is designed to have at least one of its eigen-values at the origin. The synthesis is then formulated as an H weighted-sensitivity optimization for static output feedback (SOF) gain of a Luenberger observer.
