Active Control of Nonlinear Dynamic Response of Space-frames Using Piezo-electric Actuators

A scheme for active control of nonlinear vibration of space-structures, wherein each member is modeled as a beam-column, is presented. The expressions for shear stresses transmitted to the structural member by the distributed segmented piezo-electric actuators, which are bonded on the surfaces of the member, are derived in the general case in which the structural member is subjected to moments,...

Design of an Active Noise Control System using Plasma Actuators

In this work an investigation into improving the efficiency and performance of atmospheric glow discharge plasma actuators [1, 2] applied to aeroacoustics is conducted. Recent studies have demonstrated that plasma actuator technology can be used to influence low Reynolds number flows. Previous work has shown that plasma actuators have the ability to produce a significant variation in the flow f...

Experimental study on active structural acoustic control of rotating machinery using rotating piezo-based inertial actuators

In this paper, two Piezo-Based Rotating Inertial Actuators (PBRIAs) are considered for the suppression of the structure-borne noise radiated from rotating machinery. As add-on devices, they can be directly mounted on a rotational shaft, in order to intervene as early as possible in the transfer path between disturbance and the noise radiating surfaces. generate the appropriate actuation signals...

A High Performance Feedback Active Noise Control System

In many active noise control (ANC) applications, an online secondary path modelling method that uses a white noise as a training signal is required. This paper proposes a new feedback ANC system. Here we modified both the FxLMS and the VSS-LMS algorithms to raised noise attenuation and modelling accuracy for the overall system. The proposed algorithm stops injection of the white noise at the op...
