Induction motors are very common in industrial applications like pumps, blowers, compressors, fans, air-conditioning systems and others. The main reason for this popularity in the industry is because they are very simple, require minimum maintenance and manufacturing costs are low. This paper is aimed to give a contribution in speed control of a 250 W three phase induction motor in an application which requires a high performance of electric drive. The Field Oriented Control (FOC) technique is implemented in order to have the required performance. This algorithm has some advantages compared to scalar control such as improved dynamics, full torque control from zero to nominal speed, decoupled control of flux and torque, higher efficiency and others. This study is done in the Simulink/MATLAB environment where the model of speed control of 250 W three phase induction motor is created. Firstly, the fifth order model of the motor is built in a stationary frame. Secondly, the Field Oriented Control technique is implemented when are found also PI regulators coefficients. In the end, Space Vector Pulse Width Modulation (SVPWM) technique was built. This is the final step of FOC to determine the pulse width modulation signal for the inverter switches in order to generate the desired three phase voltage to the motor. Numerical simulations which are presented graphically at the end of this paper shows the advantages of using FOC.
