Introduction The models of magnetic devices having a magnetic core without known parameters require the core evaluation by means of sophisticated measurement procedures and systems. For certain models, higher measurement accuracy is of key importance. For the other models, additional factors (speed, cost, measurement instruments and apparatus) may strongly limit achievement of the specific meas...
متن کاملTitle: Fast, Preisach-like characterization of hysteretic systems Authors:
Proposed is a substantially simplified, Preisach-like model for characterization of hysteretic systems, in particular magnetic systems. The main idea is to replace a two-dimensional Preisach density with just two real functions, describing in a unique way the reversible and irreversible processes. As a byproduct of our model we prove, that the major hysteresis loop alone is insufficient to prod...
متن کاملComputer Realization of the Continuous Preisach Hysteresis Model
Preliminary notes The Preisach hysteresis model is widely used in different engineering disciplines, for example: electrical engineering, mechanical engineering and so on. The Preisach model is a unique tool to describe in a mathematical consistent way the hysteresis phenomenon with non-linearities and memories. The Preisach hysteresis model is discrete, however this paper presents a continuous...
متن کاملPreisach Model Identiication of a Two-wire Sma Actuator
In recent years, the Preisach hysteresis model has emerged as the model of choice for the behaviour of many smart materials, such as shape memory alloys (SMA). This research treats the identi cation of Preisach models for a di erential SMA actuator. The traditional identi cation technique is applied, and several models are derived for the actuator. It is seen that the classical Preisach model i...
متن کاملHysteresis Nonlinearity Identification Using New Preisach Model-Based Artificial Neural Network Approach
Preisach model is a well-known hysteresis identification method in which the hysteresis is modeled by linear combination of hysteresis operators. Although Preisach model describes the main features of system with hysteresis behavior, due to its rigorous numerical nature, it is not convenient to use in real-time control applications. Here a novel neural network approach based on the Preisach mod...
