Discrete electronic analog controllers have been largely replaced by digital controllers using microcontrollers or FPGAs to implement PID algorithms. However, discrete analog PID controllers are still used in niche applications requiring high-bandwidth and low-noise performance, such as laser-diode controllers.
Principal ideal domains are mathematical objects that behave like the integers, with respect to divisibility: any element of a PID has a unique factorization into prime elements (so an analogue of the fundamental theorem of arithmetic holds); any two elements of a PID have a greatest common divisor (although it may not be possible to find it ...

The PID algorithm in the controller restores the actual speed to the desired speed in an optimum way, with minimal delay or overshoot, by controlling the power output of the vehicle's engine. Control systems that include some sensing of the results they are trying to achieve are making use of feedback and can adapt to varying circumstances to ...
I suggest Astrom' PID Controllers Theory, Design and Tunning (1995, not sure if there is a newer edition) and, **much** more relevant and concise about this particular topic is O'Dwyer's Handbook of PI and PID Controller 3rd edition (2009). In fact, O'Dwyer's chapter 2 is entirely about different forms for PID controllers.
Open-loop control and feedback control, often based on canned PID control algorithms, are much more widely used. [4] [5] [6] There are three types of control systems: open loop, feed-forward, and feedback.

In particular, the integers are a PID, so one can always calculate the Smith normal form of an integer matrix. The Smith normal form is very useful for working with finitely generated modules over a PID, and in particular for deducing the structure of a quotient of a free module. It is named after the Irish mathematician Henry John Stephen Smith.
