A jump-jet aircraft has a control system shown in figure. Assume that z > 0 and p > 0. The system is open loop unstable (without feedback). Given that z < p – 1 and 0 < k < ∞. The condition for the closed loop stability is _____
1
\(k > \frac{{p\left( {p - 1} \right)}}{{\left( {p - 1} \right) - z}}\)
2
\(k < \frac{{p\left( {p - 1} \right)}}{{\left( {p - 1} \right) - z}}\)
3
\(k > \frac{{p\left( {p - 1} \right)}}{{\left( {p - 1} \right) + z}}\)
4
\(k < \frac{{p\left( {p - 1} \right)}}{{\left( {p - 1} \right) + z}}\)
