Ludwig's WRAP-UP
In summary, "controlled by" is a versatile and grammatically sound phrase used to express influence, authority, or regulation. As Ludwig AI notes, it's a standard phrase found in numerous contexts, from formal news reports to encyclopedic entries. While it's essential for indicating who or what has power over something, you should also be mindful of passive voice constructions, which can sometimes be replaced with more direct active voice sentences. Keep in mind that while the phrase is correct and widely used, related phrases such as "governed by" or "managed by" can offer subtle variations in meaning. Considering these alternatives can help you find the most precise wording for your intended message.
