Consider a system with a loop gain T(s) where T(s) has a pole at s = 1 + j. Analyze the stability based on the Nyquist Criterion.
💡 Hint: Draw the s-plane and evaluate the pole's location.
Design a Nyquist plot for a hypothetical feedback function T(s) = (10)/(s^2 + 4s + 10). Explain the plotted features that indicate stability.
💡 Hint: Look for gain crossover and phase margin in your analysis.
