Indirect vector control of a variable frequency induction motor drive (VCIMD)

Abstract

The principle of vector control of electrical drives is based on the control of both the magnitude and the phase of each phase current and voltage. Matlab/ Simulink has been performed for assessment of operating features of the proposed scheme. PI speed controller are designed in this paper, Test response of the developed variable speed drive along with simulated response are given and discussed in detail for torque, speed and current. Modeling of induction motor with the complete vector control scheme (indirect) is investigated to show the optimal response of the control system.
