Query: Optimal and Sub-optimal Feedback Controls for Biogas Production   We revisit the optimal control problem of maximizing biogas production in
continuous bio-processes in two directions: 1. over an infinite horizon, 2.
with sub-optimal controllers independent of the time horizon. For the first
point, we identify a set of optimal controls for the problems with an averaged
reward and with a discounted reward when the discount factor goes to 0 and we
show that the value functions of both problems are equal. For the finite
horizon problem, our approach relies on a framing of the value function by
considering a different reward for which the optimal solution has an explicit
optimal feedback that is time-independent. In particular, we show that this
technique allows us to provide explicit bounds on the sub-optimality of the
proposed controllers. The various strategies are finally illustrated on Haldane
and Contois growth functions.
