Stirling-cycle cryocooler active vibration control

Proceedings of IEEE International Conference on Control and Applications, 2002
A cryogenic cooler capable of continuously maintaining the required cryogenic temperature is one of the critical elements enabling space-borne surveillance sensors to detect cold objects against a space background or warm objects against an Earth background.

The model of active vibration control based on giant magnetostrictive materials

Smart materials and structures (Print), 2019
Vibrations that occur in various engineering structures have potential damage to the structural system. An important structural system is the intelligent structure containing magnetostrictive materials.

Active Vibration Isolation by Adaptive Control

Journal of Vibration and Control, 2001
In this paper, an adaptive controller known as a self-tuning regulator (STR) is employed for active vibration isolation. Numerical simulation of the developed STR for active vibration isolation of a simple two- degree-of-freedom mechanical system subject to external disturbances is carried out.

Evolutionary adaptive active vibration control

Proceedings of the Institution of Mechanical Engineers, Part I: Journal of Systems and Control Engineering, 1997
This paper presents an investigation into the development of an adaptive active control mechanism for vibration suppression using genetic algorithms (GAs). GAs are used to estimate the adaptive controller characteristics, where the controller is designed on the basis of optimal vibration suppression using the plant model.

Study on Active Vibration Control

Advanced Materials Research, 2013
This paper analyses the active vibration control technology on the piezoelectric ceramics car-body pieces in fuzzy control Strategy. Adaptive controllers, based on fuzzy logics, are synthesized for the control of vibration of body structure. Piezoelectric element, control system and body structure have been combined to be a intelligent response system ...

Active control of mechanical vibrations

Bell Labs Technical Journal, 2009
Recent advances in digital signal processing and actuation technology have opened the door to applying active control to reducing mechanical vibrations and acoustic noise. Because these techniques work best at lower frequency, they complement conventional passive damping techniques, which are most effective at higher frequencies.

Active Control for Vibration Damping

1988
Active control laws are developed for an LSS-type structure to damp vibrations. High frequency modelling uncertainties lead to the necessity for a robust control design. The Linear Quadratic Gaussian with Loop Transfer Recovery (LQG/LTR) control design technique is a particular robust design technique selected for use in designing a damping control ...

Active vibration control of a hoop truss structure with piezoelectric bending actuators based on a fuzzy logic algorithm

Smart materials and structures (Print), 2018
Active vibration control of large flexible space structure is a challenging topic in the system dynamics and control of spacecraft. This paper proposes a novel approach for vibration control on a large hoop truss structure, typically used as mesh ...
