  2. Overshoot (signal) - Wikipedia

    en.wikipedia.org/wiki/Overshoot_(signal)

    The magnitude of overshoot depends on time through a phenomenon called "damping." See illustration under step response. Overshoot often is associated with settling time, how long it takes for the output to reach steady state; see step response. Also see the definition of overshoot in a control theory context.

  3. Integral windup - Wikipedia

    en.wikipedia.org/wiki/Integral_windup

    Within modern distributed control systems and programmable logic controllers, it is much easier to prevent integral windup by either limiting the controller output, limiting the integral to produce feasible output, [5] or by using external reset feedback, which is a means of feeding back the selected output to the integral circuit of all ...

  4. Step response - Wikipedia

    en.wikipedia.org/wiki/Step_response

    Figure 5 is the Bode gain plot for the two-pole amplifier in the range of frequencies up to the second pole position. The assumption behind Figure 5 is that the frequency f 0 dB lies between the lowest pole at f 1 = 1/(2πτ 1) and the second pole at f 2 = 1/(2πτ 2). As indicated in Figure 5, this condition is satisfied for values of α ≥ 1.

  5. Proportional–integral–derivative controller - Wikipedia

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

    Pressure control provided only a proportional control that, if the control gain was too high, would become unstable and go into overshoot with considerable instability of depth-holding. The pendulum added what is now known as derivative control, which damped the oscillations by detecting the torpedo dive/climb angle and thereby the rate-of ...

  6. Control theory - Wikipedia

    en.wikipedia.org/wiki/Control_theory

    The definition of a closed loop control system according to the British Standards Institution is "a control system possessing monitoring feedback, the deviation signal formed as a result of this feedback being used to control the action of a final control element in such a way as to tend to reduce the deviation to zero." [12]

  7. Configuration management - Wikipedia

    en.wikipedia.org/wiki/Configuration_management

    It covers the process of controlling modifications to the system's design, hardware, firmware, software, and documentation. Configuration Status Accounting: includes the process of recording and reporting configuration item descriptions (e.g., hardware, software, firmware, etc.) and all departures from the baseline during design and production.

  8. Loop performance - Wikipedia

    en.wikipedia.org/wiki/Loop_performance

    Loop performance in control engineering indicates the performance of control loops, such as a regulatory PID loop. [1] Performance refers to the accuracy of a control system's ability to track (output) the desired signals to regulate the plant process variables in the most beneficial and optimised way, without delay or overshoot.

  9. Ringing (signal) - Wikipedia

    en.wikipedia.org/wiki/Ringing_(signal)

    An illustration of overshoot, followed by ringing and settle time. In electronics, signal processing, and video, ringing is oscillation of a signal, particularly in the step response (the response to a sudden change in input). Often ringing is undesirable, but not always, as in the case of resonant inductive coupling. It is also known as ...
