Conclusion:
1)As P value increase from 2 to 20, system becomes more relatively stable because root locus bends towards right half of the s- plane.
2)As increasing P value number of asymptotes are constant but centroid or intersection points moves left half of the s-plane
3)If P---infinite, s=-p, pole become insignificant and system becomes more relatively stable and system is critically damped rise time, delay time increases and system time constant increases.
