How to find the range of the gain K for a system is stable using the system's open loop root locus plot. You will learn to use the MATLAB functions rlocus, step, and how to navigate root locus plots.

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.

I show how to interpret the locations of poles in the S-plane, and how they are tied back to system requirements. Don't forget to subscribe! I'm on Twitter @BrianBDouglas!

Get the book-in-progress with any contribution for my work on Patreon - https://www.patreon.com/briandouglas This video presents two special cases that you can encounter when filling out the Routh Array. The first case is when there is a zero in a row with at least one non-zero element following it, and the second case is when there is an entire row of zeros. I explain how to continue filling out the Routh Array for each of these cases and provide a little insight into what they mean for the system stability.

Part 2 of explaining how to draw the root locus for a (negative) feedback control system. Showing that the root locus must be symmetric about the real axis and that it also exist on the real axis to the left of an odd number of the open-loop poles or zeros. Correction: The forth rule about the real axis should be: "The real axis root locus exists to the left of an odd number of poles or zeros of G(s)H(s)." Sorry for the confusion!

Example problem on how to find range of K given block diagram for the system to be stable

09:54
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 purpose of controller stability analysis is to determine the range of controller gains between lower and upper limits that lead to a stable controller. KcL≤Kc≤KcU The principles of stability analysis presented here are general for any linear time-invariant system whether it is for controller design or for analysis of system dynamics. Several characteristics of a system in the Laplace domain can be deduced without transforming a system signal or transfer function back into the time domain. Some of the analysis relies on the roots of the transfer function denominator, also known as poles. The roots of the numerator, also known as zeros, do not affect the stability directly but can potentially cancel an unstable pole to create an overall stable system. A first point of analysis is whether the system converges or diverges. This is determined by analyzing the roots of the denominator of the transfer function. If any of the real parts of the roots of the denominator are positive then the system is unstable. A simple rule to determine whether there are positive real roots is to examine the signs of the polynomial. If there are mixed signs (+ or -) then the system will be unstable because there is at least one positive real root. Before modern computational methods, there were several methods devised to determine the stability of a system. One such approach is the Routh-Hurwitz stability criterion. The leading left edge of a table determines whether the system is stable for or any nth-degree polynomial.

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).

The concept of stability is presented, requiring a bounded output for any bounded input. The stability of the closed loop blending process is calculated for a proportional control law. The root locus plot is introduced to visualize the dependence of stability on controller gain.
