This study investigated a flux oriented control of Active Mass Damper (AMD) induction motor for buildings under seismic ground motion. Composed primarily of an induction motor, a mass bloc and a ball screw, the electric-type active mass damper (AMD) system is free from noise problems, oil leakage, and labor-intensive maintenance that commonly are associated with hydraulic AMD systems. In this study a five steel-frame structure is implemented with the electric type AMD system. An LQR control algorithm is adopted for displacement reduction of the structure subjected to ground acceleration. The indirect flux oriented control method is used for the control of the AMD induction motor. The great advantage of this method resides in the fact that we do not need to use the amplitude of the rotor flux but only its position. Numerical simulation is performed under the conditions of a Kanai-Tajimi power spectral density function of ground motion and the simulation results show that the torque supplied by the induction motor pursuits its reference provided by the LQR control algorithm. Significant reductions of 65% and 78% respectively in the roof acceleration and roof displacement have been reached. And the proposed system is recommended for practical implementation.
