Abstract: The DC motors are widely used in daily life. To improve the control performance of the smart car, we establish the brush DC motor mathematical model,which can control well the accuracy and optimize performance. Besides,we also provide a method of getting the mathematical model parameters of the motor which has unknown SPECS by experiments, namely, the step response measurement of transfer function parameters.

Key words: transfer function, step response method, RS-540 DC motor, smart car
