摘要
In order to accurately describe the asymmetric rate-bias-dependent hysteresis of a Fe-Ga alloy magnetostrictive actuator, a comprehensive model, which is composed of a phenomenon model, describing hysteresis by the modified Bouc-Wen hysteresis operator, and a theoretical model, representing the dynamics characteristics, is put forward. The experimental system is setup to verify the performance of the comprehensive model. Results show that the modified Bouc-Wen model can effectively describe the dynamics and hysteresis characteristics of the Fe-Ga alloy magnetostrictive actuator. The results highlight significantly improved accuracy in the modelling of the magnetostrictive actuator.
