Sample period
Also: control period, Ts
The intended time between successive discrete controller updates.
It shapes numerical approximation, delay, bandwidth, processor utilization, and gain interpretation; actual periods include jitter.
- Units
- seconds (s)
- Formula
f_s = 1/T_s
Example A 10 ms period corresponds to 100 Hz nominal updates.
Common misconception A delay call alone does not guarantee the requested period because computation also takes time.
