Field Oriented Control Of Induction Motor Using dsPIC30F6010A

Abstract

The work related to Field Oriented Control of Induction Motor with field weakening capability using dsPIC30F6010A prototype board and simulation using PSIM is car- ried out in this proposed work. A flux-weakening technique is applied when extension of the motor speed beyond base speed is desired. The field-oriented control, with its flux/torque decoupling feature is realized with a digital PWM controller in rotating d-q coordinate system. This kind of control requires a relatively powerful DSP(digital signal processor) along with the relevant peripherals to make vector control a prac- tical proposition. The DSP board used, dsPIC30F6010A programmed using MPLAB IDE and C-compiler soft ware for this type of drive application. The proposed work is carried out on a 2HP Induction motor and tested successfully for required performance. The program required for 5HP motor performance is also developed for lift application.
