Feedback Control Strategy

To prevent thermal runaway while ramping down the residual concentration, use

feedback control to adjust the coolant temperature Tc based on measurements of the

residual concentration Cr and reactor temperature Tr. For this application, we use a

cascade control architecture where the inner loop regulates the reactor temperature and

the outer loop tracks the concentration setpoint. Both feedback loops are digital with a

sampling period of 0.5 minutes.
