Robust and Adaptive Active Vibration Control Using an Inertial Actuator

Vibration control of an automotive engine using active mounts

In this research, vibration control of national engine (EF7) using active mounts is studied for two different mounting layouts. The first layout is based on the current engine mounting of national engine (system of three passive mounts), but the hydraulic mount is substituted by an active mount. The other mounting layout contains 4 mounts, 2 of which are active ones and the others are passive m...

Vibration control of flexible structures using fusion of inertial sensors and hyper-stable actuator/sensor pairs

This paper discusses sensor fusion techniques that can be used to increase the control bandwidth and stability of active vibration isolation systems. For this, a low noise inertial instrument dominates the fusion at low frequency to provide vibration isolation. Other types of sensors (relative motion, smaller but noisier inertial, or force sensors) are used at higher frequencies to increase sta...

Robot Vibration Control Using Inertial Damping Forces

H∞ robust control design of active structural vibration suppression using an active mass damper

A mathematical model of any real system is always just an approximation of the true, physical reality of the system dynamics. There are always uncertainties in the system modeling. This paper outlines a general approach to the design of an H∞ control of an active mass damper (AMD) for vibration reduction of a building with mass and stiffness uncertainties. Linear fractional transformation (LFT)...

Adaptive Piezoelectric Absorber for Active Vibration Control

Abstract: Passive vibration control solutions are often limited to working reliably at one design point. Especially applied to lightweight structures, which tend to have unwanted vibration, active vibration control approaches can outperform passive solutions. To generate dynamic forces in a narrow frequency band, passive single-degree-of-freedom oscillators are frequently used as vibration abso...
