Another name for an open loop is what?

An open loop is commonly referred to as a feed forward loop. This terminology emphasizes the nature of open-loop systems, which operate without using feedback to adjust their performance. In a feed forward loop, the system takes inputs and processes them to deliver an output without relying on the output to influence its operation.

This concept stands in contrast to closed-loop systems, where feedback is essential for regulating the output based on the actual performance compared to desired performance. In a feedback loop, changes in output would affect the input in subsequent cycles, enabling corrections and adjustments. However, in an open loop, the system does not monitor or adjust based on output, which is why it embodies a feed forward mechanism.

Understanding this distinction is crucial in instrumentation and control systems, as it helps in recognizing how different systems operate under varying feedback conditions.
