Abstract

Based on the step response data, an identification method is presented to estimate the parameters of second-order inertial systems. Using special data points, the transcendental equations are changed into algebraic equations which are easy to solve for computing the parameters of the transfer function models. The numerical examples indicate that the proposed approaches can estimate the parameters of the systems.
