By using the open loop transfer function for a control system, how would you then sketch the Nyquist plot by hand?
I'm aware you'd substitute any \$s\$ term for \$j\omega\$ and then rationalise the denominator by moving the \$j\$ terms to the numerator. But from this point forward I am unable to get to the point where I can plot the rough shape of the Nyquist plot. Any break-down of the steps would be greatly appreciated.
