Matrix Converter Fed Field-Oriented Control of Permanent Magnet Synchronous Motor

摘要

Field-oriented control of permanent magnet synchronous motor fed by matrix converter is designed. By introducing space vector modulation for inverter, AC-AC matrix converter is equivalent to AC-DC-AC substitution. Then, perfect PWM technology is adopted for virtual rectifier and virtual inverter of substitution whose modulating schedule and model are analyzed and deduced. i_d =0 of field-oriented control for matrix converter fed permanent magnet synchronous motor is built up. Finally, simulations are carried out, and simulating results show that the proposed system is feasible and valid, which provides theoretical foundations for experimentation.
