Examples of techniques for controlling a cooling system for an internal combustion engine using feedback linearization are provided. In one example implementation, a computer-implemented method includes receiving, by a processing device, desired temperature targets. The method further includes receiving, by the processing device, temperature feedbacks. The method further includes calculating, by the processing device, a desired temperature derivative for each of the desired temperature targets. The method further includes calculating, by the processing device, desired coolant flows from the desired temperature derivative for each of the desired temperature targets using feedback linearization. The method further includes calculating, by the processing device, actuator commands from the desired coolant flows using an inverted hydraulic model. The method further includes implementing, by the processing device, the actuator commands in actuators in the cooling system.
