چکیده مقاله
The effectiveness and feasibility of the continuous sliding mode control CSMC is investigated through comparison with conventional linear quadratic regulator LQR control in isolated bridges When these bridges are subjected to ground motions with large intensity, the deck displacement becomes excessively large So, in this study three design goals are studied: reduction of column response, reduction of bearing response and reduction of both responses The column isolator deck system can be idealized as a two degree of freedom lumped mass system Several approaches are used for the determination of sliding surface as an important parameter in this control algorithm The results show that the sliding mode control with appropriate sliding surfaces achieves outstanding control performance and is more effective in mitigating seismic responses of nonlinear isolated bridges
