<![CDATA[In the current development of industrial technology, electricity has been used as the prime mover. One of them is an electric motor, the most widely used is an induction motor. This is because induction motors have advantages in easier maintenance, relatively affordable prices, sturdy construction, and more reliable performance. Examples of the use of induction motors are in modes of transportation, both land, sea and air. However, induction motors still have a weakness which lies in the speed of themotor which is complicated to control. So the speed control research was carried out using the Direct Torque Control (DTC) method. To set the condition of the inverter switching using Space Vector Modulation (SVM). Speed, torque and flux control is carried out with a PI controller, where the PI parameters are determined using the RST-pole placement tuning method. Pole determination is based on the desired design performance criteria. The results of PI parameter on speed, torque, and flux arerespectively Kpω = 1277,59 and Tiω = -0,96, KpT = 8,4 and TiT = -0,2, Kpψ = 67,7 and Tiψ = 0,17. After testing, under no-load condition and a set point of 157 rad/s the system was able to reach a steady state with a steady state error of 0,6% within a settling time of 0,25 seconds. Under conditions of variation in load of 100 Nm, 200 Nm, 300 Nm, the system was able to reach steady state with steady state errors of 0,6%, 0,9%, and 1,2% in settling times of 0,25 seconds, 0,27 seconds, and 0,28 seconds, respectively. Keywords: Three Phase Induction Traction Motor, Direct Torque Control, Space Vector Modulation, PI-Digital Controller, RST Controller. DAFTAR PUSTAKA[1] S. E. Nugroho, W. Aribow, Ibrohim and A. C.
