A New approach to Sensor less vector control of induction motors
Journal Title: International Journal of Marketing and Technology - Year 2011, Vol 1, Issue 7
Abstract
Induction motors are used in variable speed drive applications with the development of vector control technology. There are two forms of vector or field oriented control: direct field orientation, which relies on direct measurement or estimation of the rotor flux, and indirect field orientation, which utilizes an inherent slip relation. Though indirect field orientation essentially uses the command (reference) rotor flux, some recent works using the actual rotor flux are reported to achieve perfect decoupling Estimation rather than measurement of the rotor flux is an alternative approach for both direct and indirect field orientation that has received considerable attention. In this paper the rotor flux and speed control of induction motor is presented using a novel technique in which the induction motor model in rotor reference frame is considered. Controllers used for sensor less control of the drive. The estimation technique works well and the sensor less speed control scheme can achieve fast transient response as good as that of the induction motor with sensors and at the same time maintain a wide speed control range. This paper presents work on flux and speed estimation of induction motor by considering the rotor reference frame of the Induction motor using MATLAB / Simulink.
