Abstract
System and methods of controlling a plurality of motors based on a motor motion attribute, such as rotor position, velocity, or acceleration, which simulate the properties of a mechanical differential, including a pure differential, a limited slip differential, and/or a locking differential. The method may be employed in a number of applications, including, without limitation, a paper handling system, such as an inserter, to control the nips of a pinless cutter of an inserter, and in a vehicle.
