Various semi-active control devices have been widely investigated to reduce the responses of structures under earthquake, including variable orifice dampers, and controllable fluid dampers (e. g. MR dampers). Due to the inherent nonlinear nature and uncertainty of the semi-active control system based on magnetorheological (MR) fluid damper, an improved back propagation (BP) algorithm is proposed,...
Structural control is one of the most promising strategies for the field of structural vibration. Based on the basic characteristics of the structural vibration control, the categories of structural control method are introduced. The control algorithms are systematically reviewed from the aspects including active control, semi-active control, and neural-fuzzy control. Finally, the existed problem...
MR damper is one of the most promising new devices for vibration control of structures. Numerical modeling of MR damper behavior is a crucial topic that must be implemented before successful control of structural vibration is feasible. Based on the basic characteristics of the MR damper control, the application in MR damper control of intelligent theory is introduced. The algorithms are systematically...
One challenge in the use of semi-active technology is in developing nonlinear control algorithms that are appropriate for implementation in full-scale structures. Based on the basic characteristics of magnetorheological (MR) damper, the structural control algorithms are introduced. The nonlinear control algorithms are systematically reviewed from the aspects including clipped optimal control, LQR...
Structural intelligent control system (SICS) is the advanced field of seismic engineering discipline. Due to the inherent nonlinear nature and uncertainty of the semi-active control system based on magnetorheological (MR) fluid damper, an improved back-propagation (BP) algorithm is proposed, which divides the actual structure model into a mechanism model part and a timevarying error model part. By...
