Claim 19:
20. The process as recited in claim 16, further comprising:
determining, using the at least one processor, a measured delta temperature in response to the at least one processor receiving the temperature signal from the at least one temperature sensor;
determining, using the at least one processor, a low-pass filtered measured delta temperature based on the measured delta temperature associated, a time step, a loop instant number, and a time constant associated with a low-pass filter;
determining, using the at least one processor, a low-pass filtered measured delta temperature set point based on an unfiltered delta temperature set point, the time step, the loop instant number, and the time constant;
determining, using the at least one processor, a nominal delta pressure based on a coefficient of laminar flow associated with the coolant, a viscosity of the coolant at the average temperature of the coolant, an estimated flow rate of the coolant, a coefficient of turbulent flow associated with the coolant, and a density of the coolant at an average temperature of the coolant;
determining, using the at least one processor, a delta pressure set point based on the nominal delta pressure, the low-pass filtered measured delta temperature, and the low-pass filtered measured delta temperature set point; and
determining, using the at least one processor, the feedback correction based on the delta pressure set point and the pressure drop.
