Nyquist (Polar) Plot for with addition of pole and zero

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

Title: Sketch Nyquist (Polar) Plot 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 Nyquist (Polar) plot for a given system and verify the results using MATLAB.
2. Analyze the effect of the addition of poles and zeros on the polar plot based on changes in time domain specifications.

Aim: The aims of the experiment are to

1. Sketch the polar plot 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.
