It is easier to obtain the transfer function of the relation between the voltage and the angular velocity than between the voltage and the angular displacement in DC motor. I analogi z e the closed loop transfer function of the relation between the reference signal and the angular displacement out of the voltage-angular velocity transfer function using the encoder mathematical modelling, 1/(TsS). To assure the validity of the encoder mathematical modelling, I make a DC motor feedback control system set-up using micro-controller ATmega88 and real DC motor IG32GM. In the set-up I ac q uire the data to track the target position. As a result, the time index in time domain such as rise time, delay time in mathematical modelling is similar to the time index in set-up system. The error between two systems is in less than 10 % . Therefore this encoder mathematical modelling in continuous domain is useful to apply the real DC motor feedback system in digital domain using micro-controller.
