What are open loop systems?

Career: Open Loop

Open loop systems are control systems in which the output is not measured or fed back for comparison with the input. In these systems, actions are taken based solely on input conditions and predetermined instructions, without using feedback to adjust performance. This makes them generally simpler and less expensive than closed loop systems, but also less accurate or responsive to external changes. Common examples include basic electric toasters or washing machines that run for a set time regardless of actual results.
