The phrase "a primary control on" is correct and usable in written English.
It can be used when discussing a significant factor or influence affecting a particular outcome or process.
Example: "Temperature is a primary control on the rate of chemical reactions."
Alternatives: "a key factor in" or "a major influence on".
The parameters of this cumulative relationship, determined experimentally, predict that, should the IC Model be a primary control on mammalian tooth sizes, m2 will occupy one third of total molar occlusal area, regardless of whether m1 is larger than m3 or vice versa.
The wind is a primary control on dispersal of ash and gas.
The preserved aeolian facies types exert a primary control on reservoir quality.
Metal speciation is a primary control on metal mobility and bioavailability in the environment, and adsorption reactions can play a significant role in this process (e.g., [1]).
From previous studies it is understood that the heterogeneity of late winter SWE is a primary control on patterns of SCD.
Hydrological dynamics act as a primary control on ecosystem function in mountain peatlands, serving as an important regulator of carbon fluxes.
A primary control layer, based on applying decoupled droop control methods to the inverters, was proposed and analyzed, demonstrating its capability to share power and keep frequency and voltage within prescribed ranges under load changes.
We found that anthropogenically-enhanced inorganic N inputs act as a limited primary control on the spatial distribution of N2O saturations in heavily eutrophied parts of the lake only and that overall, lake N2O production and emission are not raised as significantly as expected due to high N inputs.
We compare our method to two classic ones relying on droop control: the first one with only primary control on both frequency and voltage and the second one with an additional secondary frequency control operated by the slack device.
On the other hand, a set of complementary domains exerts primary control on the aaRS isopotential surface formation.
A dependence on the people is, no doubt, the primary control on the government; but experience has taught mankind the necessity of auxiliary precautions".
