Vibration damping method of mechanical flexible structures for various vibration actuator and sensor positions employing second order all-pass filter

摘要

In the present invention, there is disclosed an active vibration damping method of elastic mechanical flexible structures by controlled action of damping force at a point, which differs from the point where vibration sensor is situated. This method of the present invention solves a problem of regulation loop instability with a little damped mechanical structure and a different type of feedback for same oscillation modes.
