HW 9 part(c)...do we use model(4) results that match 2nd order Pade approx, sampled data model results?

In HW9, problem 1(a), it appears that to evaluate the given compensator design, we need to use averaged model (4) results that match the first order Pade approximation results of the sample data model. Then in 1(c), we are asked to use the "more accurate" model to design the compensator. Are we expected to use the modified averaged model (4) whose results match the 2nd order Pade approx. of the sampled data model (or do we still use the first order results)?

    Hi Nitish,

    I think you can just use the "more accurate model" from table 12.3 in the book, in combination with table 1 in the exercise.
