Abstract:
1. An irrigation system comprising: a central pivot; a series of mobile towers connected to the central pivot and to one another by support structure, each mobile tower having wheels and a motor for driving at least one of the wheels; and a control system for operating the motors to maintain alignment of the mobile towers and the central pivot while preventing power used by the motors to propel the mobile towers from exceeding a configurable maximum power threshold, the control system being configured to determine in which sequence to operate the motors to maintain alignment of the mobile towers while operating at most the maximum number of motors that can be operated simultaneously without exceeding the configurable maximum power threshold, the control system comprising a computing device that turns off a motor of a least mis-aligned mobile tower whose motor is running if the maximum number of motors is already operating.
