AC drives based on full digital control have reached the status of a maturing technology in a broad range of applications, ranging from low-cost to high performance systems. In the field of the drive of the electric machines, the elimination of the mechanical speed sensor can present an economic interest and improve safety of operation. With speed estimation, sensorless vector control is possible,...
The most industrial applications use the variation of the torque, speed and/or position in process, for which extremely severe specifications are needed. In the field of the drive of the electric machines, the elimination of the mechanical speed sensor can present an economic interest and improve safety of operation. One thus tries to make fulfill the speed measurement by implementing in a Digital...
