Problem 52 in Chapter 10 mentioned a measurement based technique to design fixed-structure controllers, which does not require system identification. In that problem, we assumed a plant transfer function of (Khadraoui, 2013)

Again, the interested reader is directed to the reference for further study. In this problem, however, we use the design and analysis techniques developed in this and the previous chapters.

0.1111(4s + 5s+ 1) G(s) = s4 +3.1s3 + 0.85s2 +0.87s + 0.1111
