SYSTEM BREAKDOWNWe are going to analyse the biological system in a control perspective way. Our 3 main aims are; 1) Suggesting a realistic model for the system 2) Comparing the wet lab result with our model 3) A standard description of how our overall system intends to work.
MODELLets first look at how our initial system works. The flow diagram below gives a brief description of it;
The above flow chart can be reconstructed into a control block diagram;
The script below shows how each block parameters are designed
Our next step is to simulate the model, which brings about an interesting design practise which my team has employed. Which is, how does the photoreceptor works? And how does it affect the system when light intensity varies? A point to note; each ODE’s tends to a steady state after some time. Therefore we have suggested that: Each constant varies with the amount of light shined on the system and as well achieves a steady state at a certain point. Without the presence of red light, the concentration of EnvZP, (EnvZP)OmpR and OmpRP should increase. Therefore the constants which affect the rate of reaction of those should decrease with intensity; which is K1, K-2, Kk and Kt. Whereas K-1, K2, K-k and Kp increase as intensity increases.
Initial concentration of: EnvZ = 1M, EnvZP = 1M, (EnvZP)OmpR = 1M, OmpRP = 1M, OmpR = 1M, EnvZ(OmpRP) = 1M.
