Abstract

Aspects of human life today are inseparable from the use of electric motors. One type of electric motor is a DC motor. DC motors play an important role as actuators for various torques and speeds because of their many advantages, one of which is easy-to-control speed settings. The DC current that is passed through the field winding is used for the flux in the machine. The voltage induced in the armature winding varies with the commutator and brushes. It is this change in the induced voltage in the armature winding that causes the rotational movement of the rotor so that its speed varies with changes in the load torque. This research begins by determining the parameters of the DC motor. After that, look for the value of DC motor transfer function. After getting the results of the system's frequency response, then designing a bode diagram sketch and designing a DC motor control system with the addition of a lead compensator which aims to speed up the response and increase the stability of the system. The results obtained from this study are to analyze the response values of the electromagnetic torque and the rotational speed of the rotor compared to changes in time. At the initial starting of a DC motor with a lead compensator designed for a 2.5% overshoot reduction, the resulting electromagnetic torque has a maximum value of 3.3% higher than the 5% overshoot reduction. Whereas at the initial start-up of a DC motor with a lead compensator designed for a 5% over shoot reduction, the resulting rotor speed response has a maximum value of 0.94% higher than the 1.25% overshoot reduction.
