Abstract

In this paper, we consider economic optimal control of single-cell protein (SCP) production in a U-loop reactor. The model of the U-loop reactor contains both ordinary and partial differential equations. Consequently, the optimal control problems are large-scale. The optimal operating profile for the SCP production is an unstable attractor. Therefore, we consider two simultaneous collocation-based approaches for solving the optimal control problems. We implement these two approaches in C, and we use IPOPT to solve the involved nonlinear program (NLP). Finally, we present a performance study that demonstrates the feasibility of solving economic optimal control problems that involve the U-loop reactor in real-time.
