Document Summary
Supplemental problems chapter 4: for the process modeled by. = 4 y1 6 y2 + 2u. Find the four transfer functions relating the outputs (y1, y2) to the inputs (u1, u2). The ui and yi are deviation variables: a single irreversible chemical reaction, B takes place in a nonisothermal continuous stirred-tank reactor (cstr), as shown in following figure. The reaction rate expression is given by: r kc. It is desired to derive the transfer function between reactor concentration ca and coolant temperature, tc. Someone has proposed the following approach: first derive the individual transfer functions between ca and t and between t and tc. Then the desired overall transfer function will be obtained from the product of the two individual transfer functions: Briefly indicate your opinion of the proposed approach. Is there a better approach? (note: it is not necessary to actually derive any transfer functions. )
