Abstract: Bioreactor control has become an active area of research in recent years.This paper deals with the operation, mathematical modeling and IMC based design of a biochemical reactor. The dynamic behaviour was studied by changing the main operating parameters – dilution rate and its disturbance rejection for a step input change using autotuning of the controller is determined. We have found that the regimes strongly depend on the operating conditions. The bioreactor model was implemented in Matlab Simulink and the results of simulation for a stable and unstable processes are presented comparatively. Transient response characteristics for the processes are evaluated and discussed.
Keywords: Biochemical Reactor, Autotuning of PID Controller, Stable Operating Point, Mathematical Modelling, Transient Response.
