Design and implementation of a sliding-mode observer of the rotor flux
نویسنده
چکیده
Abstract— A sliding-mode observer for the rotor flux and speed of an induction motor is presented in this paper. It is also proposed another observer that is a modification of the original one to reduce the errors and improve the obtained speed results. The observer is used in a sensorless Indirect Field Oriented Control (IFOC). The original and modified observers are executed in an experimental platform that contains a digital signal processor (DSP) TMS320F2812, a 370W induction motor and an IGBT inverter. Experimental results show that the modified observer produces better results than the original, and globally the work produced good results.
