Consider a negative feedback system where G(s) =1/(s+1) and H(s) =K/s(s+2). The closed loop system is stable for
A. K>6
B. 0<K<2
C. 8<K<14
D. 0<K<6
Answer:D
Consider a negative feedback system where G(s) =1/(s+1) and H(s) =K/s(s+2). The closed loop system is stable for
A. K>6 B. 0<K<2 C. 8<K<14 D. 0<K<6
Explanation: Using Routh array, for stability k<6.
