“…Therefore, in this research, the first approach is considered and some changes are made in its control strategy to make it applicable to an FSTPI drive. The authors earlier reported on experimental results of an FSTPI drive in the high-speed region by proposing a flux weakening strategy to improve its characteristics (27) . However, this strategy did not fully optimize the characteristics of an FSTPI drive in the high-speed region because the current was not adequately controlled and limited.…”

This paper proposes a field-weakening control strategy to optimize the torque production and motor efficiency of a four-switch three-phase inverter-fed induction motor drive in the high-speed region. A method to control the torque component current (I q ) and the flux component current (I d ) of the field-weakening region is proposed. The feasibility of the proposed control strategy is verified through a simulation and validated experimentally. The results show that the speed-torque characteristics and the motor efficiency are improved in the high-speed region.
