About Paper:

Over-actuated systems are present in many modern applications (i.e. air vehicles, automotive, robotics) due to redundancy or performance. This means that there exist many possible control actions that can achieve the same reference setpoint(s). As such, there exists a need to optimize these control actions around some given metric. This work describes the design, implementation, and validation of a proposed control strategy in an over-actuated single-phase cooling loop such that two objectives are met: (1) target mass flow rates in two fluid branches are achieved as a result of the control actions and (2) the set of control actions selected minimizes power consumption. The system is modeled using the pressure drop across each fluid branch. From the model, mass flow rates at varying control states are used to determine the possible space of control actions. The power consumption can then be modeled as a function of the control actions in order to identify the combination of mass flow rates that minimizes this quantity. The control strategy is tested on a scale system consisting of two controllable flow rates and three available control actions. Future directions involving optimization with respect to different metrics, beyond power consumption, are also discussed.
