Question #1 (60 pts): A closed-loop digital control system having a proportional controller is given in the following figure
\(G_{1}(s)=\frac{1-\exp (-T s)}{s(s+1)}, G_{2}(s)=\frac{1}{s}, G_{3}(s)=\frac{1-\exp (-T s)}{s(s+2)}\)
where \(\exp (\cdot)\) denotes the standard exponential function.
a) Obtain the overall transfer function of the closed-loop system.
b)Obtain the range of proportional gain (i.e., \(\mathrm{K}\) ) that guarantees the system stability via Jury's
Stability Test.
c) Assume that the input of the system is a unit step input (i.e., \(r(t)=u_{s}(t)\) ), obtain the gain value from the range obtained in (b) that provides the least possible steady-error (i.e., \(\left.\lim _{k \rightarrow \infty} e[k]\right)\) value. What is the least possible steady-state error value for your selection?
