A controller for controlling flow of coolant to one or more components of a vehicle is disclosed. The controller determines respective amounts of heat expected to be rejected by the one or more components of the vehicle in a steady state of operation at current operating conditions of the one or more components, and generates a feedforward flow control signal based at least in part on the determined amounts of heat and a target temperature for the one or more components. The controller generates a controller output signal based at least in part on the feedforward control signal, and provides the controller output signal to the cooling system to control flow of coolant to the one or more components of the vehicle from the cooling system in accordance with the determined amounts of heat expected to be rejected by the one or more components of the vehicle.
