Abstract:
A fan speed control system for a machine is disclosed. The control system may include a fan to provide a flow of coolant to the machine. The system may further include a first sensor configured to generate a first signal indicative of an operational parameter of the machine, a second sensor associated with the fan to generate a second signal indicative of an actual speed of the fan, and a controller communicatively coupled to the fan, the first sensor, and the second sensor. The controller may be configured to generate a third signal indicative of a desired fan speed based on the first signal, and a fourth signal indicative of a difference between the desired fan speed and the actual fan speed. The controller may drive the fan based on the third signal and the fourth signal.
