Abstract
Magnetorheological (MR) dampers are the most promising devices for vibration control applications because it has many advantages such as mechanical simplicity, high dynamic range, low power requirements, large force capacity and robustness. In this paper, a new approach for studying the forward and inverse dynamical behavior of an MR damper using Non-Linear Autoregressive Models with Exogenous Inputs (NLARX) is presented. NLARX is a built-in function related to the identification toolbox, MATLAB/Simulink software, used to identify the nonlinear behavior of dynamic and engineering systems. The training and validation of the proposed model are done theoretically using the data generated from the modified Bouc–Wen model. Validation data sets representing a wide range of working conditions of the damper show that the use of the NLARX model to predict the forward and inverse dynamical behavior of MR dampers is reasonably accurate.
