This video explains why we need design tools like the Routh-Hurwitz Criterion, Bode Plots, Nyquist Plots, and Root Locus. This is an introduction into the difficulties of determining the stability of closed loop systems and why we can't use the same techniques that we use for determining the stability of open loop systems. I hope this video gets you interested and excited to learn more about these design tools!

Stability analysis determines the range of controller gains that are expected to create a stable response. The stable response can either reach a new steady state with oscillations or no oscillations. A root locus plot is a quick way to show stability versus instability and any expected oscillations.

root locus for open loop control system

Views: 21715
Education 4u

The two fundamental equations for root locus construction are derived by considering the closed loop characteristic equation's magnitude and phase. One of these provides a method for computing the design parameter, K, from the desired closed loop pole locations of a root locus plot. An example is used to illustrate the approach.

The Root Locus method is a fantastic way of visualizing how the poles of a system move through the S-plane when a single system parameter is varied from 0 to infinity. I show how to interpret the locations of poles in the S-plane, and how they are tied back to system requirements.

In this video I go through some of the common questions I've received on my other root locus videos.
1) Why do we call the poles of a system the roots?
2) How do I plot the damping ratio line on a root locus plot?
3) How is the damping ratio equation cos(b) = zeta work when zeta is greater than 1?
4) How do I solve for the gain of system using the root locus plot?
5) How can I use Matlab to plot the root locus?

Root Locus | Control System Experiment | LabVIEW
n control theory and stability theory, root locus analysis is a graphical method for examining how the roots of a system change with variation of a certain system parameter, commonly a gain within a feedback system. This is a technique used as a stability criterion in the field of classical control theory developed by Walter R. Evans which can determine stability of the system. The root locus plots the poles of the closed loop transfer function in the complex s-plane as a function of a gain parameter (see pole–zero plot).
