MRAS Based Sensorless and Sensor Vector Control and Smooth Transient Between Them

open access: yesCommunications, 2011
Dynamic control, like vector control is an essential feature of every modern AC drive. In some cases it might be very important to provide continuous operation in case of encoder failure.

Current vector control challenges in the fight against malaria in Brazil [PDF]

open access: yesRevista da Sociedade Brasileira de Medicina Tropical, 2019
In Brazil, malaria is an important public health problem first reported in 1560. Historically, fluctuations in malaria cases in Brazil are attributed to waves of economic development; construction of railroads, highways, and hydroelectric dams; and ...

Impact of the motor magnetic model on direct flux vector control of interior PM motors [PDF]

open access: yes, 2011
The stator-field-oriented, direct-flux vector control has been proven to be effective in terms of linear torque control and model independent performance at limited voltage and current (i.e. in flux weakening) for AC drives of various types.

Local vector control applied to current control

open access: yes2016 IEEE 2nd Annual Southern Power Electronics Conference (SPEC), 2016
Current control is the most basic control loop for a current controlled inverter-fed machine. Current controllers fall into two categories depending on the reference frames they operate in — rotating reference frame controllers, and stationary frame controllers.
