The phrase "as a closed loop" is correct and usable in written English.
It can be used in contexts discussing systems, processes, or feedback mechanisms that are self-contained or self-regulating.
Example: "The feedback system operates as a closed loop, ensuring that any deviations are immediately corrected."
Alternatives: "in a self-contained manner" or "as a feedback loop".
Speed control is realized as a closed loop control.
The target is constructed as a closed loop circulating system cooled by a helium refrigerator.
Like this: But René Spitz's observations vividly showed that an infant animal's metabolism cannot exist as a closed loop.
A production line with a limited number of carts or pallets is regarded as a closed loop manufacturing system.

In reality, however, it's a bludgeoning rant against a single state — New Jersey — which it presents as a closed loop of Mercedes-owning administrators, obstructive teachers' unions and corrupt school boards.
Regenerating the main media oxygen, water, and carbon as well as demonstrating a closed loop are essential milestones for an efficient and sustainable LSS.
5 As a generalisation of indirect comparisons, when more than two treatments are being compared indirectly, and at least one pair of treatments is being compared directly as well as indirectly (a closed loop is present), both direct and indirect types of data can be used to estimate effects in a mixed treatment comparison (MTC) meta-analysis using a Bayesian or frequentist framework.
Another interesting observation is that for the debutanizer example, the nonlinearities seem to lead to biased estimates also with the closed loop subspace method, and the choice of controller gain appears to be just as important as the use of a closed loop subspace identification method for the accuracy of the estimates.
The overall control system to be developed, in this work is considered to be composed of cardiovascular system duly triggered by an intelligent pacemaker system as operated in a closed loop manner with unity negative gain in the feedback path.
The production cycle of goods was also different from today, functioning as more of a closed loop, within which merchants and peddlers didn't just sell goods, they reclaimed what the family couldn't reuse — scraps of metal, cloth rags, bits of glass — and turned them into new goods.
