The potential application of smart materials is being investigated by various researchers inthe perspective of building intelligent systems. A smart structure consists of distributed actuatorsand sensors with associated processors to analyse and control t... see more

In this paper, the two positive position feedback controllers (PPF) are proposed to reduce the longitudinal and angular vibrations of the nonlinear spring pendulum system which simulated the ship roll motion. This described by a four-degreeof- freedom sys... see more

Dynamic vibration absorbers of indicator type are analyzed. In such absorbers direct interaction between object and absorber is absent. It is shown that such absorbers are effective even for simple controllers. For analyze the linear matrix inequalities a... see more

Severe vibrations such as earthquakes threaten to demolish or cause damage to built structures during their lifetime. Mitigation of such damage can be done by using control devices such as actuators. In this paper, an algorithm is proposed to analyze the ... see more

The active vibration control system for 3D mechanical structures is presented in the paper. The steel space framework which consists of 126 steel bars and 44 aluminium joints is a subject of our investigations. It is equipped in two piezoelectric stacks w... see more

The paper describes an active vibration control system for a structure of two degrees of freedom. The system comprises two elastically connected bodies moving along vertical guides. The system structure is additionally provided with two electrodynamical l... see more

The article deals with the analysis of active vibration control of a rotor which is supported by journal bearings. The oil film between the journal and bushing induces the rotor instability, which causes rotor vibrations if rotational speed is greater tha... see more

This article investigates vibration rejection for a continuous smart structure using piezoelectric bimorph patches. Such a structure has inherent nonlinearities, such as hysteresis and creep, and the whole system may experience unexpected disturbances, un... see more

This paper presents experimental identification and vibration suppression of a flexible manipulator with piezoelectric actuators and strain sensors using optimal multi-poles placement control. To precisely identify the system model, a reduced order transf... see more
