To accurately characterize the mechanical behavior of magnetorheological elastomer (MRE) under a wide range strain amplitude, excitation frequency, and magnetic field, viscoelastic fractional derivative was introduced, modified Bouc-Wen model based on for MRE in nonlinear region established. The can describe hysteretic characteristics region, but it cannot simulate magneto-viscoelasticity frequ...

Bu bildiride, açık döngülü piezo-elektrik doğrusal sürücüler için yüksek çözünürlükte histerez telafisi gösterilmektedir. Piezo-elektrik malzemelerde yapıları gereği mevcut olan doğrusalsızlıklar, Bouc-Wen modeli kullanılarak model tabanlı bir kontrol algoritması ile telafi edilmiştir. Telafi için kullanılan yöntemin histerez davranışında zaman, değişen frekans ve farklı hareket genişliği neden...

In this paper, an event-triggered sliding mode control with hysteresis is proposed for motion tracking of the piezoelectric actuator (PEA) in presence uncertainties, disturbances, and nonlinearity characteristics. First, dynamic model characteristics described by Bouc-Wen model. Second, design (ETSMC) PEA system discussed proves stability using Lyapunov’s Law. Finally, The PZS001 THORLAB...

The Bouc–Wen nonlinear hysteretic model has many control parameters, which been widely used in the field of seismic isolation. isolation layer is most important part system, can be effectively simulated by model, and system reflect different dynamic characteristics under parameters. Therefore, this paper mainly studies analyzes influence factors based on incremental harmonic balance method, pro...
