Abstract:

In this paper, a vector control strategy with UVM for seven-phase induction motor drives is presented and tested.Based on the spatial decomposition model of 7-phase induction motor, the d-q fundamental spatial components are controlled using vector control strategy. However the harmonic components of currents are generated by the harmonic components in the 3rd and 5th harmonic subspaces.Combined with voltages in harmonic subspaces set to be zero, the UVM with harmonic current elimination is proposed.Based on the simulation, experiment results verify the feasibility and effectiveness of the strategy proposed on the 7-phase IM experimental setup with DSP core TMS320F28335.
