Abstract

Abstract

Based on the principles of linear optimal active control, this paper develops an optimal active control algorithmcommanding the structure displacement, velocity and acceleration simultaneously, and derives the revisal Riccati equationfrom this. Moreover, the semiactive control has been used for the pulsating wind vibration response of multifunctionalvibration -absorption megaframe structure by means of magnetorheological damper. The result seems to indicate that the sem-iactive controlmay be able to more significantly reduce the vibration acceleration response of the main and the secondaryframes, and to more effectively suppress the vibration displacement response of the main frame than the passive control.
