چکیده مقاله:

Natural hazards such as earthquakes have threatened the life of human beings during the history.As a consequence, the vibration mitigation of structures has caught great importance. Activecontrol of structures is one of the rapidly emerging areas in the concept of structural control. Thispaper presents a control method to deal with this subject when the dynamics of the structure ishysteretic and the parameters of the structure contain uncertainties. The hysteresis behavior of thestructure is modeled using Bouc-Wen equation and the uncertainty is considered in its parameters.For control purpose, sliding mode method and its adaptive version are used. The salient point ofadaptive sliding mode technique is that it does not use the uncertainty bounds in its controller; thisis correspondent to the fact that the estimation of the structural parameters may not be exact. Theefficiency of the proposed method is shown with a simulation.

Hybrid Adaptive Synchronization of Hyperchaotic Systems with Fully Unknown Parameters

In this paper, an adaptive control scheme is developed to study the hybrid synchronization behavior between two identical and different hyperchaotic systems with unknown parameters. This adaptive hybrid synchronization controller is designed based on Lyapunov stability theory and an analytic expression of the controller with its adaptive laws of parameters is shown. The adaptive hybrid synchron...

Nonlinear Vibration Analysis of a cantilever beam with nonlinear geometry

Analyzing the nonlinear vibration of beams is one of the important issues in structural engineering. According to this, an impressive analytical method which is called Modified Iteration Perturbation Method (MIPM) is used to obtain the behavior and frequency of a cantilever beam with geometric nonlinear. This new method is combined by the Mickens and Iteration methods. Moreover, this method don...

Adaptive Control of Unknown Dynamic Hysteretic Systems

This paper first discusses the adaptive control for the hysteresis described by PrandtlIshlinskii model. Then, the adaptive control for the continuous-time linear dynamical systems preceded with hysteresis described by Prandtl-Ishlinskii model is considered. The relative degree and the upper bound of the order of the linear dynamical system are assumed to be known. The contribution of the paper...

Passive , Nonlinear , Mechanical Structures for Seismic Attenuation

Gravitational wave detectors aim to detect strain perturbations of space-time on the order of 10−21–10−22 at frequencies between 1 Hz and a few kHz. This space-time strain, integrated over kilometer scale interferometers, will induce movements of suspended mirrors on the order of 10−18–10−19 m. Seismic motion in this frequency band varies between 10−6 m and 10−12 m. Required seismic attenuation...

Nonlinear Optimal Control Techniques for Vibration Attenuation Using Magnetostrictive Actuators

This paper addresses the development of a nonlinear control design for attenuating structural vibrations using magnetostrictive transducers operating in nonlinear and highly hysteretic operating regimes. We consider as a prototype a thin plate subjected to exogenous pressure waves and controlled via Terfenol-D transducers at the plate edges; however the methodology is sufficiently general to en...
