This work proposes a closed-loop control strategy for a coupled set of biological reactors that was designed as part of a regenerative wastewater treatment system for NASA's advanced life support system for long-duration human space missions. Two types of control strategies are demonstrated, one that uses a set of decentralized single-loop controllers and another that uses a supervisory model-based control strategy. Using an experimental testbed that is 1/20th the actual size of the full-scale regenerative wastewater treatment system, the closed-loop performance of the biological reactors is compared in the presence of feed concentration disturbances.
