## Root locus design using Matlab

Root locus design is a control system development technique in which the designer edits the compensator poles, zeros, and gains in the root locus diagram. It examines how the roots of a given system change in relation to modifications in certain system’s parameters. Root locus design was invented to determine the stability of a system. It uses a special protractor to determine an angle and draw the root locus.
Matlab is one of the programs used to create root locus design. However, students always find trouble dealing with assignments and projects on this topic due to the complexity of the concepts in this area. To avoid poor grades, they search the web for online root locus design assignment help services, hoping to find an expert to help them with their assignments. We offer this service at an affordable price and many students have benefited from the outstanding solutions we have provided to them over the years.

## Why root locus design is common among system developers

Root locus is one of the most effective ways to determine the stability of your system. For instance, you can create root locus designs to:
− Find out if the system is 100% stable as well as the degree of stability
− Predict the performance of the system without having to find the actual solution of the system’s differential equations.
− Analyze the method or technique by which the system should be modified to give the desired performance
When creating root locus designs, the characteristic of the closed loop system’s transient response must be closely related to the location of the poles of the closed loop. If your system has a defined loop gain, the location of the poles of the closed loop will be based on the value of the chosen loop gain. From a design point of view, a simple gain modification may move the poles of the closed loop to the desired locations. If adjusting the gain does not give you the desired results, you can add a compensator to the system.

## Learn how root locus works from our root locus design tutors

According to our root locus design experts, the poles of the closed loop are the roots of the characteristic equation of the closed loop system. In Matlab, the Root Locus Plot feature helps you to plot the roots of the closed loop system’s characteristic equation. It enables you to plot all the values of the system’s parameter, mostly the gain. However, you can also plot any other variable of the transfer function of the open loop.
By using this feature, you can approximate how adding the poles or/and zeros of the open loop or modifying the value of the gain will affect the location of the poles of the closed loop. The poles of the transfer function of the closed loop are closely related to the gain as well as to the poles and zeros of the transfer function of the open loop. The values that make the transfer function of the open loop equal to -1 should satisfy the closed loop system’s characteristic equation. The root locus plot shows you how the poles and zeros of the open loop should be adjusted so that the response meets the performance specifications of the system.
Having experience in drawing the root locus by hand is important, as it helps you interpret the root loci generated by Matlab. It also helps you master the concept of root locus designs quickly. If you would like to have the concept of the open loop and closed loop expounded further by a professional, feel free to hire root locus design tutors from our website. Also, if you are struggling with an assignment from this topic, we have a team of highly experienced root locus design assignment helpers who can assist you with it.

## Root locus for non linearity explained by root locus design homework help experts

Our providers of online root locus design homework help service argue that all real control systems are nonlinear. Hence, developers usually use linear analysis to predict real-world models. However, there is a type of nonlinear systems for which we can perform significant analysis. These include systems in which there are no dynamics in the nonlinearity. In such systems, nonlinearity is well predicted as a gain that increases or decreases in size with the increase or decrease of its input signal. To quantitatively describe the behavior of systems showing such linearity, we need to consider the nonlinear element as a gain that depends on the size of the signal.
