摘      要：Indirect field oriented control(IFOC)has become a widely adopted solution for AC motor *** IFOC controls torque and rotor flux linkage via q-and d-axis ***,deadbeat-direct torque and flux control(DB-DTFC)has emerged as a promising motor control strategy for the future,which manipulates *** ***-gap torque and stator flux linkage are decoupled and independently controlled over each switching *** flux linkage is used as a separated degree-of-freedom to manipulate losses dynamically without compromising torque dynamics and torque *** voltage-limited operations,direct selection of *** DB-DTFC to fully utilize the dc bus voltage and produce fast torque.A single control law is used over a wide speed *** paper aims to provide a comparative overview of the two motor controls regarding their sensitivity to parameters,current-and voltage-limited operation,loss manipulation,and torque ripple during signal *** on the comparison,the ultimate objective is to demonstrate the opportunities and remaining challenges in DB-DTFC.
