However, in Systems where Operators must diagnose the root cause of the fault to compensate effectively, then the Interface must support analytical redundancy for every element in the System by making all of the signals in the
feedback control loop accessible to the Operator: The output signal from each element must be compared with the expected value, given the input signal and a normative model of the element.
if it guarantees the stability of the
feedback control loop for all possible variations of parameters (2).
Experimental closed loop data from this
feedback control loop was collected for 1.5 h (including start-up time).
Switching power supplies rely on
feedback control loops to ensure that the required voltage and current are maintained under varying load conditions.
As can be seen, the response in standard
feedback control loop has considerable oscillations.
Since then, the concept of using existing data to automate
feedback control loops has blossomed into a suite of available features that provide extremely practical use with very little engineering intervention.

Feedback Control Loops," In: "Proceedings of IEEE International Conference on Control Applications," Kohala Coast, Hawaii, U.S.A.
Feedback control loops for pH are preferred to feedforward.
Feedback control loops are the main building blocks in all modern heating, ventilating, and air-conditioning (HVAC) control systems.
"The ReFlex Power supplies replace the hardware-defined transfer functions of traditional outer
feedback control loops and protective supervisory loops with firmware-defined, high-speed FPGA-based equivalents.
