Robust performance enhancement using disturbance observers for hysteresis compensation based on generalized Prandtl?Ishlinskii model

Popis výsledku v původním jazyce

This paper presents an approach employing disturbance observers to enhance the performance of inverse-based hysteresis compensation based on the generalized Prandtl?Ishlinskii model in feedback control reference-tracking applications. It is first shown that the error resulting from inexact hysteresis compensation is a bounded signal. A disturbance observer (DOB) is designed to cancel its effect and improve the closed loop robust tracking performance in the presence of plant dynamics 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 an eigenvalue at the origin. The synthesis is formulated as a sensitivity optimization forstatic output feedback (SOF) gain of a Luenberger observer. A linearization heuristic is then implemented to solve the bilinear-matrix-inequality (BMI) constrained semidefinite program (SDP) for a (sub)optimal static gain.
