| Summary: | High-performance variable speed drives require a better transient performance compared with the steady-state operation. Nowadays, vector control and direct torque control (DTC) are popular methods for high performance drives. This paper presents a new vector control method for voltage-source inverter fed induction motors using look-up tables. The proposed method uses a predetermined look-up table instead of a much more time consuming pulse width modulation (PWM) procedure in conventional vector control to produce inverter gate signals. This approach gives a quick torque response like vector control and gives reduced ripple in steady state compared to DTC. The common mode voltage emissions are reduced based on the application of only odd or only even voltage vectors in each sector in which the stator flux lies. The common mode voltage repetition rate is reduced by using this methodology. To validate the proposed method numerical simulations have been carried out and the simulation results confirm the effectiveness of the proposed method. |
