  2. Proportional–integral–derivative controller - Wikipedia

    en.wikipedia.org/wiki/Proportional–integral...

    The form of the PID controller most often encountered in industry, and the one most relevant to tuning algorithms is the standard form. In this form the K p {\displaystyle K_{p}} gain is applied to the I o u t {\displaystyle I_{\mathrm {out} }} , and D o u t {\displaystyle D_{\mathrm {out} }} terms, yielding:

  3. Closed-loop controller - Wikipedia

    en.wikipedia.org/wiki/Closed-loop_controller

    The PID controller is probably the most-used feedback control design. If u(t) is the control signal sent to the system, y(t) is the measured output and r(t) is the desired output, and e(t) = r(t) − y(t) is the tracking error, a PID controller has the general form

    A Piping and Instrumentation Diagram (P&ID or PID) is a detailed diagram in the process industry which shows process equipment together with the instrumentation and control devices. It is also called as mechanical flow diagram (MFD).

    Physical Interface Device, a class of a USB device; PID controller (proportional-integral-derivative controller), a control concept used in automation; Piping and instrumentation diagram (P&ID), a diagram in the process industry which shows the piping of the process flow etc. Principal ideal domain, an algebraic structure

  6. Setpoint (control system) - Wikipedia

    en.wikipedia.org/wiki/Setpoint_(control_system)

    In the context of PID controller, the setpoint represents the reference or goal for the controlled process variable. It serves as the benchmark against which the actual process variable (PV) is continuously compared.

    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.
