Abstract :
A motor power feeder cable can be used for power supply and to transmit the speed information of the motor to the controller by applying a power line communication method. The method produces latency to the feedback loop and hence, decreases the performance of the system. A disturbance observer is implemented in a control loop to increase the system stiffness to load disturbances.
