Week 09
Bode Plots
I follow the saved course materials and calculations from modeling through stability, root locus, and frequency response.
What I connect in this unit
A Bode plot builds total response by adding each pole's and zero's magnitude slope and phase contribution on a logarithmic frequency axis. An asymptotic sketch exposes the corner structure, while the exact curves locate gain and phase crossover frequencies.
Concept map
- Logarithmic frequency
- Asymptotic sketches
- Gain crossover
- Phase crossover
Technical anchor
Each first-order pole adds -20 dB/dec after its corner. Mark ωgc where |L(jωgc)|=1 and ωpc where ∠L(jωpc)=-180° as two distinct crossover frequencies.
How I review it
Factor the loop into constant gain, origin terms, and real poles or zeros; draw their straight-line contributions, then correct magnitude and accumulated phase near each corner.
Connection to the full course
Unit 9 of 12. Unit numbers organize the concepts found in the materials and do not reproduce an attendance schedule.
