= 1 s-1 (5 points) Controller design is about balancing competing objective. In this problem you will explore the trade-off between tracking performance and control effort. Consider the plant P(s) 8 and controller C(s) = K. Assume a unity feedback loop with reference r(t) and output y(t) (the same we have been using in class). (a) Find the closed-loop transfer function T(s) = Y(s) R(s)*
