Description
I'm using the control package with python 3.10 in Pycharm and Jupiter lab.
I have stumbled upon a possible issue while trying to create a Nyquist plot for a simple system
import control as ct
s = ct.tf('s'))
plant_1 = 1/(s*(s + 5)*(s + 7)))
ct.nyquist_plot(plant_1)
The result I'm getting is this:
While in MATLAB I'm getting different results
clear all;
close all;
clc;
s = tf('s');
plant_1 = 1/(s*(s + 5)*(s + 7));
nyquistplot(plant_1)
Is there a limitation that might be causing this issue or am I missing something?
