Resumo
In this work, the horizontal response of a vertical transportation with nonlinearities under excitation by guide rail deformations is analyzed. In order to improve the comfort of passengers, a control strategy based on optimal linear feedback control using MR damper is used. The control force of the damper is a function of the voltage applied in the coil of the MR damper that is based on the force given by the controller. Numerical simulations are performed in order to study the nonlinear behavior of the adopted mathematical model. In addition the robustness of the proposed control technique is tested considering parametric errors and noise measurement. The results confirm that the control strategy using MR damper can be effective in reduce the vibration of the vertical transport.
