Cargo velocity control for cargo handling systems

A control system for a cargo handling system is disclosed. The control system may be configured to advance larger containers at a slower speed than smaller containers. For instance, all containers may be initially advanced by the same first velocity control signal. At the expiration of a certain time period, all containers may thereafter be advanced by a different velocity control signal (from the first velocity control signal) that should least substantially maintain the velocity of the container as it existed at the time of the expiration of the noted time period. The length of the time period (for advancing the container at the first velocity control signal) may be varied based upon the size of the containers such that larger containers are accelerated for a shorter time than smaller containers and which in turn should then advance larger containers at a lower velocity compared to smaller containers.
