1. A control system, comprising:
two or more devices each having a respective internal sensor and each having a respective operable element, each device having a communication subsystem and configured to self-detect one or more device properties of the operable element, the device properties resulting in output having one or more output properties;
at least one memory which stores, for each device, correlation data between the one or more device properties and the one or more output properties for that device; and
one or more controllers configured to:
detect the one or more device properties self-detected by each device from the respective internal sensor,
determine a speed variable of each device,
correlate, for each device, based on the stored correlation data, the speed variable and the detected one or more device properties, to the one or more output properties for that device,
determine, for each device, a value of the one or more output properties for that device which result in combined output of the devices achieving an output setpoint, and
co-ordinate control of each device to operate their respective one or more device properties, based on the stored correlation data, their respective determined value of the one or more output properties for that device.
