1. An irrigation system comprising: a plurality of interconnected spans, a plurality of tower structures upon which interconnected spans are supported, each of a plurality of tower structures comprising an adjustable drive for selectively driving a tower structure at a selected speed, a plurality of sensors, each of which is associated with a corresponding span from a plurality of interconnected spans and is configured to determine the alignment of the corresponding span from a plurality of interconnected spans, and a plurality of variable-speed drive control units, each of which communicates with a corresponding variable-speed drive and a corresponding sensor, and is configured to control a selected speed of the corresponding variable-speed drive in order to maintain a predominantly linear relative orientation of adjacent spans from a plurality of interconnected spans along a generally longitudinally oriented axis, while the selected speed of the corresponding control unit of the variable speed drive depends on 2. The irrigation system of claim 1, wherein the at least one sensor is configured to determine an angle between a first respective interconnected span from a plurality of interconnected spans and a second corresponding interconnected span from a plurality of interconnected spans, wherein the corresponding variable speed drive control unit is configured to determine a selected rotation speed in order to maintain a predominantly linear mutual orientation of adjacent spans from a multitude of interconnected spans1.
