Question

The root locus method consists of determining in the s-plane the desirable positions of the poles of a control system in order to achieve the desired performance. This graphical method is a powerful tool for analyzing and designing closed-loop (feedback) control systems. Below is a graph showing the application of the root locus method of any transfer function.

 

Regarding the graph, evaluate the following statements:

 

I. The open-loop pole is located at s = -2.

II. The open-loop zero is located at s = -1.

III. The root locus in the s plane comprises the interval of s \epsilon [-2 1].


What is stated in:

Imaginary Axis 0.1 Root Locus of G 0.05 о -0.05 -0.1 -2 -1.8 -1.0 -1.4 Real Axis gain = [0, 200] locus Х open loop poles ° zeros -1.2 -1
