Final answer:
The question describes a feedforward control strategy that does not use output feedback to control a process's inputs, unlike negative or positive feedback loops which do.
Step-by-step explanation:
The question pertains to a control strategy that operates without feedback from the output of the process control element, which only controls the inputs to a process. This describes a feedforward control strategy, as opposed to feedback control strategies which do adjust inputs based on the output (such as negative feedback and positive feedback loops).
Negative feedback loops work to keep a variable within its normal range and reduce excessive responses. Examples in biology include regulation of body temperature and blood glucose levels. Conversely, positive feedback loops intensify a response until an endpoint is reached, such as in blood clotting and childbirth.
