Full model
The complete model of our vanillin producing bacteria is shown in the next figure. The boxes around some species have now biological meaning they merely serve to distinguish between the different subcomponents of our system.
Because we want to optimize the design of the feedback loop in our system, we developed a block scheme of the bacteria. Which can be used to develop some theories about its performance.
Control theory
Control theory is an interdisciplinary branch of engineering and mathematics, that deals with the behavior of dynamical systems. The purpose is to design a controller who controls the system so that it behaves as wanted. There exists several criteria to measure the performance of the controller.
Stability
Stability means that no matter what the input signal (the blue light) is, the output (vanillin concentration) will remain finite after an infinite amount of time.
Tracking problem
This criterium is an indication of how well the output well follow the wanted reference system, we want the difference between the output and the wanted reference signal as small as possible.
