The thesis focuses on the measurement and identification of the dynamic system of a DC motor. The identification consists of measuring the number of revolutions of the DC motor, while changing the size of the motor power, and then performing a transfer function in the MATLAB computer program. The control unit consists of a C8051F342 microcontroller. The results of measuring the number of revolutions are performed by the computer program Terminal v1.9b. The conclusion evaluates the correctness of the measured results and the identified transfer function.
