pid/derivative_filter

A scenario of the PID controller, from tools/trace/scenarios/pid/derivative_filter.hpp.

– no checks

• The clang run (clang 18.1 optimized) matches the committed trace.
• The gcc run (gcc 13.3 optimized) matches the committed trace.

Shown on

These players show the same trace, with panels chosen to explain it:

• How much should the derivative be filtered? (How the PID Controller Works)

Every channel

pid/derivative_filter: every channel 1× real time

height [m] [0] [1]

setpoint [m] setpoint

command [m/s²] [0] [1]

measured_rate [m/s] [0] [1]

t = 0.000 s / 4.000 s

Keys (with the player focused): Space play/pause · ← → one sample (Shift: ten) · Home/End · [ ] speed

4 s of the control/pid scenario derivative_filter.hpp, 1001 samples every 0.004 s. The panels plot every channel that changes: height, setpoint, command, measured_rate. 1 events are marked. It has no pass criteria.
