Closed Loop Performance Metrics in Designing a Controller
Question
A process engineer is in charge of controlling a process whose model is unknown. The engineer chooses to develop the model using an empirical approach and then design a controller using the direct synthesis technique.
1. In the first stage, the engineer generates the step response of the process by exciting the process with a step. The observations collected every T = 0.05 min. are provided in q3stepres.mat (variables ystepres and tvec). Use these data to build a suitable approximate continuous-time (i.e., FOPTD or SOPTD with or without zero) model.
2. Concerned about the quality of the approximation due to the extremely limited frequency content of a step input, the engineer decides to excite the process with an input rich in frequencies. The frequencies used for excitation and the response of the process are contained in q3freqres.mat (variables Gjw and wvec). Re-estimate the approximation in (1) using the frequency response data.
3. Use the models in parts (1) and (2) to design two separate controllers using the direct synthesis technique.
4. The engineer incidentally stumbles upon a first-principles model of the process in the records:
G(s) = 0.04s2- 0.06s + 0.02
_______________________________________
s4 + 1.8s3+ 0.97s2+ 0.18s + 0.01
Use this first-principles model and a closed-loop performance metric(s) of your choice to select the controller (and hence the model) that suits the process best. Justify your choice of controller and model with suitable arguments.

WHAT OUR STUDENTS SAY
The quality of the research work and the structuring of the assignment essay was almost exactly as what our professor had asked for. The assignment expert at HwA was extremely professional with maintaining the deadline and sticking to the guidelines stipulated. Overall my experience with them has been way above satisfactory and I would recommend them to all students wanting help in writing their instrumentation engineering assignment.

While I took occasional help for my different assignments from TheReliableTutors, I kept on wondering whether they could actually help with my MBA dissertation paper. When I first approached them, they sounded confident and they already knew what is needed to be done. That was very relieving as even before my professor told me what to be done next, the dissertation expert knew what to do. I have got an “A†in my master’s dissertation report and now I have assigned them by PhD thesis paper also.

I started taking serious help from TheReliableTutor.com from my fourth semester. They helped me get good grades and made me understand the basics of Data Structure and Automata. I really needed help with those and now that I am getting help my level of confidence is increasing.
Jason Student
The best part about the assignments is the quality of writing that I have received every time. The “real world†examples collated locally from Singapore suggested by the online management assignment tutors with the corresponding requisite numbers help take the assignment several notches higher and have helped improve my grades.

Chemical Engineering assignments need accuracy and I have got that accuracy every time from the assignment help experts at TheReliableTutor with my Chemical engineering transport phenomenon assignment and chemical engineering transport phenomenon homework help. I am definitely signing up for the next semester

this is a very good website
I have 50 questions for the same test your page is showing only 28
hi can you please help or guide me to answer my assignments. thanks
hi can anyone help or guide me to my assignments. thanks
This solution is perfect ...thanks
Hello Allison,I love the 2nd image that you did! I also, had never heard of SumoPaint, is something that I will have to exolpre a bit! I understand completely the 52 (or so) youtube videos that you probably watched. Sometimes they have what you want, sometimes they don't! However, it is always satisfying when you are able to produce something that you have taught yourself. Great job!Debra 0 likes
