Week 12
Comparing Controller Designs
I follow the saved course materials and calculations from modeling through stability, root locus, and frequency response.
What I connect in this unit
Controller comparison is not a contest on one metric; it combines time-domain requirements, frequency-domain requirements, robustness, and control effort in one design decision. Simulation comparisons are meaningful only under the same plant, input, and limits.
Concept map
- Time-domain requirements
- Frequency-domain requirements
- Robustness
- Simulation comparison
Technical anchor
Annotate overshoot and settling bands on the step plot, crossover and margins on the loop Bode plot, and u(t) on a separate axis. A family of curves under plant-parameter variation exposes robustness.
How I review it
Complete the same requirement matrix for each candidate controller and note which condition fails first under gain variation or saturation, rather than ranking nominal response alone.
