Version 1b, August 1994 A procedure for modeling and simulation of arbitrary nonlinear magnetics components is presented. A set of electromagnetic primitives is described as implemented in Verilog-A. The primitives include cores, gaps, and windings that are combined to model ferromagnetic inductors and transformers. The physics of the ferromagnetic core model is described. The model is used to ...

This paper shows the Matlab/Simulink implementation of the current control in a single phase full-bridge power inverter. In order to increase the performances of the power inverter an LC filter is connected at the input. Mathematical modelling of the power inverter is based on the switching functions. Unipolar asymmetric PWM modulation method, and hysteresis current control will be analyzed for...

Hysteresis patterns of different sediment particle sizes were studied via a detailed laboratory study and modelling. Seven continuous rainfall events with stepwisevarying rainfall intensities (15, 30, 45, 60, 45, 30 and 15 mmh-1, each 20 min duration) were conducted using a 5-m× 2-m erosion flume. Flow rates and sediment concentration data were measured using flume discharge samples, and interp...

Abstract This research work proposes an equivalent approach modelling the peculiar hysteretic behavior of passive variable friction damper, for engineers who call a simplified way to simulate such damper in anti-earthquake engineering practice with acceptable accuracy. models special nonlinear via paralleling 3 basic link elements that commonly built-in commercially available structural analysi...

This paper deals with static hysteresis modeling for the PAM-based (pneumatic artificial muscles) position servosystem by means of an adaptive neuro-fuzzy inference system. The hysteretic behavior is expressed in arm position-pressure difference dependence where the output variable (arm position) depends on the history of input variable (pressure difference). In this way, a first order (until i...

The purpose of the presented work is to introduce the novel design of electrostatic energy harvester using bistable mechanism with compensational springs in gravity field capable of providing the output of several μW under the excitation of extremely small amplitude (up to 0.2g) and low frequency (10-100Hz). Presented energy harvester uses the bistable hysteresis modification to achieve low-fre...
