Description
Summary:The voltage/frequency “(V/F) control” method is considered as widely used method in industrial application for control the induction motor (IM) due to its simplicity and lower the cost. The main problems in this method are the slow response, and it cannot be applied in the applications that required smooth speed control. To solve these problems, a roust control method of indirect field-oriented control (IFOC) was developed. In this paper, a comparative study of classical V/F control and IFOC of 3-ph IM is done. The principle action for both methods are studied and then they implemented and simulated using “MATLAB/Simulink” software for a 10 HP (7.457kw) 3-ph squirrel cage type IM. Besides, the sinusoidal pulse width modulation (SPWM) technique with a proportional-integral (PI) controller has been used to control the VSI inverter in the V/F method. While, the space vector PWM (SVPWM) technique has been used to control the VSI inverter in the IFOC method. The 3-ph IM has been achieved to its desired speed with good transient time and steady state response when the step change in the torque load has applied. Therefore, the IFOC method provides smooth speed control, high performance, and fast response under different dynamic conditions compared to classical V/F method.
