Open-loop control is a type of control system that operates without feedback. In this system, the input is provided, and the output is generated based on predetermined rules or settings, without adjusting for any changes in the environment or system performance. An example of open-loop control is a simple toaster, which heats bread for a set time regardless of how toasted it becomes. This method is straightforward and easy to implement, but it can be less accurate than closed-loop systems, which use feedback to adjust their operations. Open-loop control is often used in applications where precision is not critical, such as in basic household appliances or simple automated processes.
