Abstract
An optimal controller is utilized minimize a total energy consumption of a CDU and cooling fans by optimizing a liquid pump speed of the CDU and fan speeds of the cooling fans collectively, while satisfying a set of constraints associated with liquid pump and the cooling fans. The total energy consumption includes a liquid pump energy cost and a fan energy cost. The optimal controller is to control the pump speed and fan speed at the same time to minimize the total energy cost, while keeping the processor's temperature below a predetermined reference temperature using an optimization function or model. The optimization model includes both the liquid and air cooling dynamics and converted the dynamics to a convex optimization problem. The optimization is performed to determine a set of pump speed and fan speeds such that the objective function reaches minimum, while the constraints are satisfied.
