In this study, a characterization of hysteresis in a piezoceramic stack actuator similar to those employed in an actively controlled flap (ACF) system is performed to assess the effects of hysteresis on system performance. The effect of unmodeled actuation hysteresis may significantly reduce vibration and noise reduction capabilities. A hysteresis model based on the classical Preisach model has...

In many scientific and medical applications wavefront-sensorless adaptive optics (AO) systems are used to correct the wavefront aberration by optimizing a certain target parameter, which is nonlinear with respect to the control signal to the deformable mirror (DM). Hysteresis is the most common nonlinearity of DMs, which can be corrected if the information about the hysteresis behavior is prese...

The origins of gate-induced hysteresis in carbon nanotube fi eld-effect transistors are explained and techniques to eliminate this hysteresis with encapsulating layers of methylsiloxane and modifi ed processes for nanotube growth are reported. A combined experimental and theoretical analysis of the dependence of hysteresis on the gate voltage sweep-rate reveals the locations, types, and densiti...

We use the Cellular Potts Model (CPM) to study the contact angle (CA) hysteresis in multiphase (solid-liquid-vapour) systems. We simulate a droplet over the tilted patterned surface, and a bubble placed under the surface immersed in liquid. The difference between bubbles and droplets was discussed through their CA hysteresis. Dependency of CA hysteresis on the surface structure and other parame...

The phase transition between the intermediate and normal states in type-I superconducting films is investigated using magneto-optical imaging. Magnetic hysteresis with different transition fields for collapse and nucleation of superconducting domains is found. This is accompanied by topological hysteresis characterized by the collapse of circular domains and the appearance of lamellar domains. ...

Memcapacitor is a two-port circuit element with a memory. When excited by AC current or voltage, it has a zero-crossing charge-voltage hysteresis curve. The memcapacitor hysteresis curve should be taught to engineering students or engineers, who want to work in this area. In this work, an easily-comprehensible explanation of hysteresis curve of flux-dependent memcapacitor is given using Taylor ...

Dynamic hysteresis modeling and its application in numerical field analysis are challenging tasks. This paper presents a measurement system to realize and to measure frequency-dependent behavior of ferromagnetic hysteresis. The well-known static Preisach model of hysteresis has been extended to simulate the dynamic behavior. The full paper will present the model in detail as well as its applica...

This paper tests two heuristic approaches by applying them to the magnetic hysteresis model parameter identification. Both Preisach and Jiles-Atherton hysteresis models have been used. The implemented investigated heuristics are genetic algorithm and simulated annealing. Both the heuristic algorithms efforts the knowledge of the B-H experimental points of the hysteresis loop to be modeled accor...

In some systems with hysteresis behavior like Shape Memory Alloy (SMA) actuators and Piezo actuators, we essentially need an accurate modeling of hysteresis either for controller design or performance evaluation. One of the most interesting Hysteresis non-linearity identification methods is Preisach model in which hysteresis is modeled by linear combination of elemental operators. Despite good ...
