In the pharmaceutical industry we want to describe the distribution of a drug in the body. A simple model divides the process into compartments: the dosage, the absorption site, the blood, the peripheral compartment, and the urine. The rate of change of the amount of a drug in a compartment is equal to the input flow rate diminished by the output flow rate. Figure 1 summarizes the system. Here each $x_i(t)$, $i=1,...,5$ is the amount of drug in that particular compartment. U$_0$ K$_1$ Dosage $x_1$ Absorption site $x_2$ K$_2$ K$_4$ Blood $x_3$ Urine $x_4$ K$_3$ K$_5$ Peripheral $x_5$ compartment As a team (2-3 students), work on the following tasks: 1) Develop a compartment model describes the system. 2) Represent the system in state space, where the outputs are the amounts of drug in each compartment. 3) Derive the transfer function of this system. 4) Use the transfer function to obtain the canonical form representation. 5) Use MATLAB to verify and implement your work. 6) Use Simulink to build this system. 7) Study the time responses using different drug inputs. 8) Other tasks will be added.
