A system for controlling a machine 52 includes a first controller 16, a second controller 18, and a comparator 36. During a first cycle, the first controller 16 generates a control signal to the machine while the second controller 18 generates a predicted parameter signal. During the first cycle, the comparator 36 transmits a feedback signal to the second controller if a predetermined threshold is not met. A method for controlling a machine 52 includes transmitting a control signal from a first controller 16 to the machine and generating a predicted parameter value in a second controller 18. The method further includes transmitting a feedback signal to the second controller 18 if a predetermined threshold is not met.

The present disclosure relates to a preassembled tower section (2) of a wind power plant (1) and a method of transporting a tower section (2) of a wind power plant (1). The method includes the steps of providing the tower section (2) at a preassembly site, preassembling at least one electronic subsystem (3, 4, 5) of the wind power plant (1) onto the tower section (2), and transporting the preassembled tower section (2) from the preassembly site to an installation site. In effect transport thereof is considerably simplified and a higher degree of modular design and preassembly is achieved.
