Abstract

The Preisach operator and its variants have been successfully used in the modeling of a physical system with hysteresis. In an application, one has to determine the density function describing the Preisach operator from measurements. In our earlier work, we described a regularization method to obtain an approximation to the density function with limited measurements. In this paper, we describe methods for recursively computing the approximate density function. These methods can be implemented in real-time controllers for smart actuators.
