Bode Plot

6. Phase margin indirectly estimates closed-loop
9. Lead compensator increases bandwidth by shifting crossover toward
11. Flat magnitude slope at crossover improves this time-domain parameter
12. If phase margin is 60°, approximate damping nature of dominant poles
15. A zero in right half-plane introduces phase behavior equivalent to
17. Bode stability criterion assumes system is open-loop
18. Region where magnitude slope changes but phase begins earlier than magnitude
19. Frequency at which closed-loop characteristic equation first satisfies Nyquist stability boundary condition
20. Excessive resonance peak implies damping ratio is

1. Second-order system parameter that directly determines peak overshoot via Bode phase margin
2. If magnitude at phase crossover exceeds 0 dB, gain margin becomes
3. Condition where magnitude curve slope at gain crossover equals −20 dB/decade ensuring good stability
4. When number of poles exceeds zeros by n, final slope equals −20n per
5. High-frequency asymptotic phase of third-order minimum-phase system
7. Lag compensator mainly modifies this frequency region
8. If slope at crossover is −40 dB/decade, system is typically
10. Frequency where imaginary axis poles would appear at instability
13. Integrator increases system type but reduces this stability parameter
14. If a system has two poles at origin and one zero at ω = 10 rad/s, initial slope before 10 rad/s equals (in words)
16. If gain is increased by 20 dB, gain crossover frequency generally shifts toward
