HYBRID ARCHITECTURE AND METHOD FOR ABSOLUTE POSITION TO QUADRATURE SYNTHESIS FOR MOTION DETECTION AND CONTROL

摘要

A motor-based position system includes one or more motors having a rotor. The system further includes a motor controller. The motor controller is communicatively coupled to each of the motors. The system further includes one or more encoders configured to detect an absolute position of each motor and one or more devices configured to collect inertial data. The system further includes a processing device coupled to the motor controller, one or more encoders and one or more devices. The processing device is configured to receive signals indicative of motors' absolute position from the encoders and configured to convert the received encoder signals into a format understood by the motor controller. The processing device is further configured to send the converted signals to the motor controller with low latency and configured to combine the received encoder signals with the inertial data to generate more accurate positional information.
