An Open-Loop Control System is a type of control system that operates without feedback. It sends a command to a process or device, and the output is not monitored or adjusted based on the result. This means that once the command is given, the system does not check if the desired outcome is achieved. Examples include a simple toaster that toasts bread for a set time without sensing the toast's color. These systems are often simpler and less expensive than closed-loop systems, which do use feedback. However, they can be less accurate since they cannot correct errors or adapt to changes in conditions. Common applications include basic household appliances and certain industrial processes.
