Open Loop System

An open loop system is a control system where the output has no effect on the control action, meaning it operates without feedback. It executes predetermined commands based on input signals, without monitoring or adjusting for the actual output results. This makes it simpler but less accurate and adaptable compared to closed loop systems.

Also known as: Open-loop control, Non-feedback system, Feedforward control, Open-loop control system, OLC

Why learn Open Loop System?

Developers should learn about open loop systems when designing simple, cost-effective, or predictable processes where feedback is unnecessary, such as in basic automation, timing circuits, or non-critical applications. It's useful in scenarios where environmental conditions are stable and high precision isn't required, like in some manufacturing or household devices.
