Abstract Given the step input signal, the input and output data of the SSY extensometer were recorded, respectively. With the least square method, the transfer function of SSY extensometer can be identified. Simulation results in Matlab environment verified the effectiveness of the obtained transfer function model of SSY extensometer.
