Abstract: Provided is a transport system to minimize an interference between motors of a transport vehicle. The transport system comprises: a first motor controller corresponding to a first wheel and configured to generate a first current value; a first motor system configured to move based on the first current value and provide a first position value according to the movement; a disturbance observer configured to receive the first current value and the first position value and calculate a first disturbance value affecting the first motor system; a second motor controller corresponding to a second wheel and configured to generate a second current value; a compensation current generator configured to generate a second compensation current value based on the second current value and the first disturbance value; and a second motor system configured to move by the second compensation current value and provide a second position value according to the movement.
