Open Loop

An open loop is a control system that operates without receiving feedback from its output. It follows a predetermined set of instructions regardless of what actually happens during its operation. For example, a microwave that heats for a fixed time without measuring the temperature inside is an open loop system. It doesn’t adjust based on the actual heating process. This approach is simple and cost-effective but can be less accurate if external factors affect performance, since it lacks mechanisms to correct errors or adapt to changing conditions.
