engineering recuitment UPMRC JE 2024 Mock Test Control Systems Stability Analysis Routh-Hurwitz Stability Criteria
The open-loop transfer function of a unity system is \(G\left( s \right) = \frac{{k\left( {s + 1} \right)}}{{s\left( {s - 1} \right)\left( {s + 6} \right)}}\)
The system is unstable for
1
k > 7.5
2
k = 7.5
3
0 < k < 7.5
4
Any value of k > 0
