The transfer function of the compensator is s+4/s+16. The maximum phase lead frequency and the corresponding phase is :
A. 6 rad/sec, 36.87°
B. 8 rad/sec, 36.87°
C. 6 rad/sec, -36.87°
D. 8 rad/sec, -36.87°
Answer:B
The transfer function of the compensator is s+4/s+16. The maximum phase lead frequency and the corresponding phase is :
A. 6 rad/sec, 36.87° B. 8 rad/sec, 36.87° C. 6 rad/sec, -36.87° D. 8 rad/sec, -36.87°
Explanation: Phase lead frequency is calculated when magnitude of transfer function is 1 and this is the phase cross over frequency and the phase is calculated by using the tanget formula with the transfer function.
