Design and Analysis Of Control Using Indirect Field-Oriented Controller for Induction Motors

An asynchronous motor type of an induction motor is an AC electric motor in which the electric current in the rotor needed to produce torque is obtained by electromagnetic induction from the magnetic field of the stator winding. An induction motor can therefore be made without electrical connections to the rotor as are found in universal, DC and synchronous motors. Although the design and construction inductive engines easier than DC Motors, but for velocity control and in various forms of inductive engines need more comprehensive knowledge in the design and construction of this kind. In the functions of the low - speed and also under the control of the situation, the use of sensors Hall due to various errors, with the desired results. Option in this case, Using Indirect Method Vector Control of Induction Motor that do not use the direct measurement of the air gap flux. This paper presents the vector control of induction motor using indirect method. Fundamental principles of vector control and dynamic mathematical model of induction motor are discussed. An algorithm for the implementation of vector control is lucidly presented. Analysis of the sensitivity of the parameters in the best way possible, the answer was dynamic and steady state errors. The results are validated using MATLAB/SIMULINK.
