Abstract:
An adaptive sliding mode controller for vibration control is proposed in this paper for structures embedded with
magnetorheological (MR) dampers. Civil structures and buildings are liable to damages during earthquake periods. The
application of structural control methodologies is important in order to suppress vibrations due to seismic phenomena and
dynamic loading. The use of sliding mode control is accounted for by its robustness to system uncertainties and external
disturbances while a MR damper is technologically-efficient for its vibration control and also fail-safe for an ideal semiactive
device. The control performance is enhanced by implementing an adaptive control law in estimating the system
parameters. Simulation results are included to demonstrate the effectiveness of the proposed controller in a building model
under earthquake-like excitations.
