Title:
METHOD FOR CALCULATING AND CONTROLLING OPTIMAL CONTROL FORCE OF ACTIVE MASS DAMPER
Document Type and Number:
WIPO Patent Application WO/2016/017856
Kind Code:
A1
Abstract:
The present invention relates to a method for calculating and controlling the optimal control force of an active mass damper to be used in the vibration control of a structure, and comprises the steps of: (a) sensing, by a sensor (200), in real time, the number of vibrations and acceleration responses, which are structural responses generated in a structure (S); (b) calculating, by an integral operation module (320), speed and displacement through the integration of the acceleration responses; (c) calculating, by a control force calculation module (330), optimal control force (Vinput) by using the calculated speed and displacement and a weighting function (G1) and a zero point calibration signal (G2) according to the displacement; and (d) controlling the driving of an actuator (400) according to the calculated optimal control force (Vinput), thereby controlling the flow of a moving mass through the weighting function and the zero point calibration signal and enabling stable control at the zero point. In addition, by removing signals other than those in a control mode through a band pass filter, precise control signal generation and performance satisfying a control target for each mode can be exhibited.
