【 摘 要 】

A simple procedure to estimate the transfer function parameters, based on the step response, of a system composed by a speed driver and a permanent magnet direct current motor is presented in this paper. The identification process is composed by the model selection, the acquisition and pre-processing of data, the parameter estimation and its validation. The results show that it is possible to estimate the system parameters from the step response achieving values of the normalized sum of squared errors less than 0.5 %.
