Open-Loop System

An Open-Loop System is a control system where the input or controlling action is independent of the output or changes in output. In this type of system, there is no feedback mechanism to adjust the input based on the output.

Key Characteristics:

  • Operates without feedback
  • Input does not change based on output conditions
  • Simpler design compared to closed-loop systems

Examples:

  • A toaster that operates for a set time regardless of whether the toast is done.
  • A washing machine that runs through a pre-set cycle without sensing load conditions.
  • A traffic light that changes at fixed intervals without sensing traffic flow.

While open-loop systems are simpler, they may lack precision and adaptability compared to closed-loop systems.
