Indirect Vector Control of Induction Motor using Space Vector Pulse-Width-Modulation (SVPWM)

摘要

The objective of vector control of induction machine is to allow an induction machine to be torque control through indirect control of armature. When the dynamic equations for an induction machine is transformed by means of rotating transformation methods into a reference frame that coincides with rotor flux, the results become similar to that of a DC machine. This method of decoupling the variables and controlling them independently is termed as vector control. In this paper Indirect Vector Control of Induction Motor has been simulated using MATLAB/SIMULNK environment. SVPWM plays a vital role to generate the pulses to trigger the inverter circuit. The simulation result shows that the performance of the Induction Motor is exactly the same as the directly controlled motor and also has a quick dynamic response.
