SUMMARY Prandtl–Ishlinskii (PI) model has an excellent compromise to characterize an asymmetric saturated hysteresis behavior of shape-memory-alloy (SMA)-driven systems, but it cannot consider thermomechanical relations between components of SMA-dr

In this study, a constitutive model based on Liang-Rogers’s relations is developed to characterize the effect of the excitation frequency in the hysteresis of shape memory alloys. Shape memory alloys are good candidates as smart actuators because o

Unique features of shape memory alloys make them a proper actuation choice in various control systems. However, their nonlinear hysteresis behavior negatively affects wide utilization of such materials in structure actuation. In this study, the frequ

Hysteresis is a nonlinear phenomenon which may cause inaccuracies and delay in control applications. Shape memory alloys (SMAs) have an asymmetric saturated hysteresis. In addition, the excitation frequency changes the hysteresis behavior of SMA-driv

In this article, two models are used, namely rate-independent and rate-dependent generalized Prandtl–Ishlinskii, to characterize a magnetic shape memory alloy actuator. The results show that the rate-independent model cannot consider the effect of

Hysteresis phenomenon limits the effective use of pneumatic artificial muscles in numerous driving applications. Experimental results show widening hysteresis loops and lowering displacement amplitudes by increasing excitation frequency. In this stud
