PID controllers often provide acceptable control using default tunings, but performance can generally be improved by careful tuning, and performance may be unacceptable with poor tuning. Usually, initial designs need to be adjusted repeatedly through computer simulations until the closed-loop system performs or compromises as desired.

The Ziegler–Nichols tuning method is a heuristic method of tuning a PID controller.It was developed by John G. Ziegler and Nathaniel B. Nichols.It is performed by setting the I (integral) and D (derivative) gains to zero.
The TI 73 series is a series of graphing calculators made by Texas Instruments, all of which have identical hardware. The original TI-73 graphing calculator was originally designed in 1998 as a replacement for the TI-80 for use at a middle school level (grades 6-8).
The original TI-30. The TI-30 is a scientific calculator manufactured by Texas Instruments, the first model of which was introduced in 1976.While the original TI-30 was discontinued in 1983 after several design revisions, TI maintains the TI-30 designation as a branding for its low and mid-range scientific calculators.
Texas Attorney General Ken Paxton filed a lawsuit against a New York doctor for allegedly prescribing abortion drugs to a resident in Texas, where nearly all abortions are banned.
OBD-II PIDs (On-board diagnostics Parameter IDs) are codes used to request data from a vehicle, used as a diagnostic tool.. SAE standard J1979 defines many OBD-II PIDs. All on-road vehicles and trucks sold in North America are required to support a subset of these codes, primarily for state mandated emissions inspections.
The Federal Trade Commission said there were no task scams in 2020, there were 5,000 in 2023 and then task scams quadrupled by the first half of 2024.
