Simulation of root locus and effect of adding pole and zero

This experiment is on simulation of root locus and effect of addition of a pole and a zero, and comparison of step responses of the systems

Title: Sketch Root Locus for a given system and verify results using MATLAB

Learning Outcomes: After the successful completion of this experiment, students will be able to

1. Sketch the Root Locus for a given system and verify the results using MATLAB.
2. Analyze the effect of the addition of poles and zeros on the root locus based on time domain specifications.

Aim: The aims of the experiment are to

1. Sketch the root locus for a given system using the analytical method and check the result using simulation.
2. Obtain the step response for K=1 and note down the time domain specifications.
3. Add a pole at a desired location and observe a change in the time domain specifications, and repeat the process for the addition of a zero by removing the pole.
