Reference Input

In this paper vector control with variable frequency drive used to apply speed control of a three-phase AC Asynchronous and induction machines. The flux and torque references used to obtain the current components. Proportional-Integral controllers are used to keeping the measured current components at their reference values. The stator voltage references are the output of the PI current controllers. High-performance with the smooth operation is obtained using the proposed method. The differences can be seen in behavior dynamic state. When the motor is rotating at full speed with a full load,it reaches good current waveforms very easily due to the independent PI control of torque and magnitude of flux. In high and sudden variations of the reference input, the direct command is more efficient and less demanding for the equipment. The expressions of the fundamental variables (speed, torque, flux) and equivalent phase circuit of the machine will be reviewed

This research was conducted to regulate the three phase induction motor speed regulation system. Changes in load on the motor affect the motor speed response so it does not match the set point speed. This study uses the Direct Torque Control (DTC) method in regulating the speed of an induction motor. The DTC method is a vector control method that is directly assigned to the inverter. DTC method in controlling speed based on Proportional Integral Differential (PID) control. Determination of PID tunning using two methods, namely, ziegler-nichols and cohen-coon method. The ziegler-nichols method have overshoot speeds starting at 0.8% of the setpoint, whereas using the cohen coon method there is no overshoot and the speed at stable conditions matches the setpoint.
