A new design of a hysteresis chaotic circuit is proposed. The simple circuit consists of one capacitor, one inductor, one resistor (negative) and one hysteresis VCVS. Computer simulation results, showing the existence of the double scroll attractor, are reported. Key-Words: Chaos, chaotic circuit, hysteresis, attractor, bifurcation, oscillator 1 This work was supported by the Louisiana BORSF co...

ysteresis is a nonlinear effect that arises in diverse disciplines ranging from physics to biology, from material science to mechanics, and from electronics to economics. While ferromagnetism offers a classical example, hysteresis also appears in mechanical systems (in the form of backlash and friction) and geophysical systems. In biology, hysteresis provides a mechanism that enhances the robus...

Hysteresis phenomenon occurs in all smart material-based sensors and actuators, such as shape memory alloys, piezoceramics and magnetostrictive actuators (Su, et al, 2000; Fu, et al, 2007; Banks & Smith, 2000; Tan & Baras, 2004). When the hysteresis nonlinearity precedes a system plant, the nonlinearity usually causes the overall closed-loop systems to exhibit inaccuracies or oscillations, even...

the direct torque control (dtc) of interior permanent magnet synchronous motor (ipmsm) offers simple structure and fast torque response. the conventional switching table-based dtc (st-dtc) presents some disadvantages like high torque and flux ripple and also variable switching frequency. this paper investigates the improved st-dtc strategies to reduce both torque and flux ripple in dtc of ipmsm...

Conducting polymer actuators are biocompatible with a small footprint, and operate in air or liquid media under low actuation voltages. This makes them excellent actuators for macroand micro-manipulation devices, however, their positioning ability or accuracy is adversely affected by their hysteresis non-linearity under open-loop control strategies. In this paper, we establish a hysteresis mode...

Anomalous current-voltage (J-V) hysteresis in perovskite (PSK) solar cell is open to dispute, where hysteresis is argued to be due to electrode polarization, dipolar polarization, and/or native defects. However, a correlation between those factors and J-V hysteresis is hard to be directly evaluated because they usually coexist and are significantly varied depending on morphology and crystallini...

Silicon nanowires (Si NW) are ideal candidates for low-cost solution processed field effect transistors (FETs) due to the ability of nanowires to be dispersed in solvents, and demonstrated high charge carrier mobility. The interface between the nanowire and the dielectric plays a crucial role in the FET characteristics, and can be responsible for unwanted effects such as current hysteresis duri...
