1 ChE 3015 Homework #7 – Due on Class #20, Friday 3/3/2006 (10 points) Do Workshop #9 - Modeling and Simulation of Single Loop Processes This shows how to use limited amounts of test data from a real process along with a computer simulation to design and test a controller in an “offline” manner, thus avoiding potential waste and production of off-specification products. In essence, one is taking a “digital snapshot” of a real process to design a controller for the process. In Step #’s 2-5, perform the necessary open loop dynamic modeling studies using a doublet test to determine first order plus dead time (FOPDT) model parameters and second order plus dead time (SOPDT) model parameters that describe the jacketed reactor operation near the design operating conditions. Consider the value of the ± 3 σ noise level for the jacketed reactor in designing the doublet test. Summarize your results for the above work with the format: Step # 2: Doublet test design Controller output change: 42% Æ 47% Æ 37% Æ 42% PV(exit temperature), o C: 92 Æ ?? Æ ?? Æ ?? Step #’s 3-4: Table 1 – Model of the open loop Reactor Process Model K p , o C/%CO τ p τ p1 τ p2 θ p SSE K c , %CO/ o C τ I FOPDT NA* NA SOPDT NA NA NA *NA = not applicable Note: The subscript “p” denotes the parameters determined from an open loop test by changing the controller output. Note that the Standard tuning correlation in Control Station Design Tools is to be used to calculate K c and τ I .

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
