The compensator Gc(s) =5(1+0.3s)/(1+0.1s) would provide a maximum phase shift of:
A. 20°
B. 45°
C. 30°
D. 60°
Answer:C
The compensator Gc(s) =5(1+0.3s)/(1+0.1s) would provide a maximum phase shift of:
A. 20° B. 45° C. 30° D. 60°
Explanation: Maximum phase shift sin^(-1)⁡ [(1-α)/(1+α)] and sin^(-1)⁡[1/2] = 30°.
