摘要
A sensorless motor controller (22) includes a variable link control, including a radiation-hardened field programmable gate array (FPGA) (28) and a back electromotive force (EMF) decoder circuit (30). The back EMF decoder (30) infers the position of a rotor of the motor (24). A filter (38) on the decoder (30) conditions the back EMF signal and has multiple cutoff frequencies which can be dynamically controlled by the FPGA (28) in order to compensate for phase shift in the back EMF signal. The FPGA (28) also controls a variable DC link and its digital speed control loop.
