Here are two advantages of Nichols chart analysis over Nyquist analysis: 1. The Nichols chart allows for the direct determination of the closed-loop frequency response (magnitude and phase) from the open-loop transfer function using the superimposed M and N circles. This information is not directly available on a Nyquist plot. 2. It simplifies the design of compensators because gain and phase adjustments are additive on the chart, making it easier to visualize the effects of compensation on stability margins and overall system performance.
