Query: On stability analysis by using Nyquist and Nichols Charts   This paper reviews stability analysis techniques by using the Nyquist and
Nichols charts. The relationship between the Nyquist and Nichols stability
criteria is fully described by using the crossing concept. The results are
demonstrated through several numerical examples. This tutorial provides useful
insights into the loop-shaping based control systems design such as
Quantitative Feedback Theory.
