Implementation of Indirect Rotor Field Oriented Control for Three-Phase Induction Motor Drive based on TMS320F28335 DSP

摘要

This paper presents an implementation of three-phase induction motor control based on the indirect rotor field oriented control (IFOC) principle. The parameters which are necessary to control such as stator current, rotor current, rotor flux vector, slip speed and electromagnetic torque in rotating reference frame are analysed and calculated. Furthermore, these proposed techniques are used to design the PI controller parameters for regulating the rotor flux and the electromagnetic torque. For overall driver system, the TMS320F28335 digital signal processor compatible with MATLAB/Simulink is employed. The experimental results show the high dynamic performance of the forward and reverse speed and the electromagnetic torque in four quadrants operation. The PI controller design can achieve the produced currents to control the rotor flux and electromagnetic torque in stationary and rotating reference frame based on variable motor speed control and disturbed load torque condition.
