In this paper the vibration suppression problem relative to the vertical motion of road vehicles is investigated. In particular, the goal of the research is to design control laws for active suspension systems of road vehicles in order to reduce unwanted vibrations induced by a rough road profile. The road vehicle has been represented with a quarter-car model whereas the suspension system has b...

The tracking control accuracy of the piezoelectric actuator (PEA) is limited due to its inherent hysteresis nonlinearity. A new piezoelectric-actuator model is synthesized based on two first-order transfer systems in parallel with two tuned parameters determined from one experiment. Two open-loop tracking controllers are implemented with the proposed model to compensate the hysteresis of linear...

A new approach to compensate the strong hysteresis nonlinearity in piezoelectric materials is proposed. Based on the inverse multiplicative scheme, the approach avoids models inversion as employed in existing works. The compensator is therefore simple to implement and does not require additional computation as soon as the direct model is available. The proposed compensation technique is valuabl...

The various mathematical models for hysteresis such as Preisach, Krasnosel’skii–Pokrovskii (KP), Prandtl–Ishlinskii (PI), Maxwell-Slip, Bouc–Wen and Duhem are surveyed in terms of their applications in modeling, control and identification of dynamical systems. In the first step, the classical formalisms of the models are presented to the reader, and more broadly, the utilization of the classica...

To deal with the challenges that classical Bouc–Wen model fails to precisely characterize amplitude-dependent hysteresis and asymmetric hysteresis, an improved variable parameters is presented. The proposed introduces terms parameter functions related sinusoidal excitation amplitudes into model. It has a relatively simple mathematic form can be easily identified applied for inverse feedforward ...

The paper presents an application of the Extended Energy-dependent Generalized Bouc–Wen model (EEGBW) to simulate experimental cyclic response Cross-Laminated Timber (CLT) panels. main objectives are assessing sensitivity quadratic error between and numerical data EEGBW parameters, showing fitting performance in matching CLT panels, highlighting stability nonlinear dynamic analysis with seismic...
