Cooperative Control Method of Active and Semiactive Control: New Framework for Vibration Control

Abstract

A new control design framework for vibration control, the cooperative control of active and semiactive control, is proposed in the paper. In the cooperative control, a structural system having both of an actuator and a semiactive control device, for example, MR damper and so forth, is defined as the control object. In the proposed control approach, the higher control performance is aimed by the cooperative control between the active control with the actuator and the semiactive control with the semiactive control device. A design method to determine the active control input and the command signal to drive the semiactive control device based on the one-step prediction of the control output is proposed. A simulation example of a control system design for a benchmark building is presented to show the effectiveness of the proposed control framework.

“…For further introduction to the concept of controllability with diverse applications, refer to major contributions [1][2][3][4][5][6][7][8][9][10] and related references therein. The concept of controllability with applications in engineering has been studied by many authors, a part of which can be found in [11][12][13][14][15][16] and in related references therein. Results obtained in this paper can be used in relevant applied studies in engineering, e.g., [17][18][19][20], for derivation of diverse control regimes.…”
