In this paper, vibration control is performed by using piezoelectric elements which are one of the smart actuator. An operator-based robust nonlinear control system by using robust right coprime factorization approach and a nonliliner property of hysteresis model is proposed. Considering the hysteresis in the piezoelectric actuator, assuming that an aircraft vertical tail is forced vibration mo...

Comfort, reliability, functionality performance which provide a longer life cycle requires thourogh understanding and analysis of the vibrations, this is a general rule for most of the static and dynamic when studying the functionality performance of any application. Vibrations is an extremely important issue to consider when designing various systems.The hysteresis in the dampers is very impor...

This paper provides a finite element analysis of laminated composite plates under the action moving vehicle. The vehicle is modeled as rigid body with four suspension systems, each consisting spring-dashpot. Overall, possesses three degrees freedom: vertical, rolling, and pitching motions. equations motion plate are deduced based on first-order shear deformation theory. Using Euler-Lagrange equ...
