The postal sorting machine comprises a sorting conveyor suitable for transporting postal articles in series past sorting outlets and a postal article feed unit having a magazine for loosely storing postal articles to be sorted and a separator that has a robotized arm and a vision sensor and that is suitable for picking up the postal articles to be sorted one-by-one from the magazine and for putting them on the sorting conveyor while placing them in series at constant pitch. The sorting conveyor has a flat conveyor that slopes sideways to form a jogging edge against which the postal articles are jogged by gravity.

A method for controlling a controlled system by a control device, the method may include transmitting multiple actuation signals to multiple degree of freedom (DOF) points of the controlled system; wherein the multiple actuation signals comprise multiple alternating current (AC) components that are mutually orthogonal; measuring at least one feedback signal from at least one probe point of the controlled system; wherein a number of DOF points exceeds a number of the at least one probe point; determining, based upon the at least one feedback signal, values of line search pulses to be sent to the multiple DOF points during at least one line search iteration; and performing the at least one line search iteration
