PID
A classic control feedback mechanism that regulates system behavior through a combination of proportional, integral and derivative terms. In reinforcement learning dual updates, a proportional term can be introduced to suppress oscillation.

A PID is a unique numeric identifier assigned by the operating system to each running process; in network service scenarios, a process typically listens on one or more ports.
Partial Information Decomposition (PID) was proposed by Williams and Beer in 2010.
The total mutual information for two sources equals the sum of the unique information components plus the redundant information plus the synergistic information, where the synergistic information can be negative.
Common methods for improving servo precision include using higher-precision digital servos, adding software-level PID compensation, and performing multiple samples at key positions and averaging them.
