The characteristic equation of a feedback control system is given bys3+5s2+(K+6)s+K=0. In the root loci diagram, the asymptotes of the root loci for large K meet at a point in the s plane whose coordinates are:
A. (2,0)
B. (-1,0)
C. (-2,0)
D. (-3,0)
Answer:C
The characteristic equation of a feedback control system is given bys3+5s2+(K+6)s+K=0. In the root loci diagram, the asymptotes of the root loci for large K meet at a point in the s plane whose coordinates are:
A. (2,0) B. (-1,0) C. (-2,0) D. (-3,0)
Explanation: The point is calculated by using Routh Hurwitz table and then equating the S0term equal to zero.
