Sensorless Real Time Control (RTC)
@article{Klatt2012SensorlessRT, title={Sensorless Real Time Control (RTC)}, author={Frederick William Klatt}, journal={3rd IEEE International Symposium on Sensorless Control for Electrical Drives (SLED 2012)}, year={2012}, pages={1-6} }
A new Brushless Real Time Control (RTC) method for electric motors or generators is an evolution in Sensor-less control. Very different from any derivative of Field Oriented Control (FOC), RTC uniquely eliminates all control uncertainty, including the extraneous shaft connected resolver for the specific purpose of measuring speed-position (i.e., Sensor-less). Although modified versions of RTC can be used for control of any type of electric machine, the variable speed Brushless Wound-rotor…
