L51 Numerical examples on polar plot
In this video the polar plots of five systems with diversified dynamics are sketched. In the first problem, polar plot of second order system with no zeros and a pole at origin is sketched. In the second problem a second order system having no zeros and all poles in the right half of s-plane is considered. In the third example a system with 3 poles in the left half of s-plane is considered. In the next two examples open loop unstable system and system with R. H. P. zero are considered.
