Control Systems The characteristic equation of a feedback control system is given by s³ + 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 (-1,0) (-2,0) (1,0) (2,0) (-1,0) (-2,0) (1,0) (2,0) ANSWER DOWNLOAD EXAMIANS APP
