Types of Control Systems

The major types of Control system are as follows:

Open-Loop Control Systems

Open-loop manage systems, also called non-feedback systems, function with out thinking about the machine’s output. In this setup, the controller sends commands to the system, and the device responds without any feedback mechanism. While open-loop structures are simple and value-effective, they lack the potential to adapt the changes or disturbances inside the System, making them less suitable for Applications requiring precision and reliability.
