Controllers: The Brain of the System
Controllers serve as the system’s brain. They look at the data sensors provide. Then, they figure out what adjustments are needed to meet goals. There are several types, like Proportional, Derivative, and Integral Controllers. They each handle signals in unique ways. Thanks to them, systems stay steady and work as they should.
Actuators: Performing Physical Actions
Actuators are crucial for carrying out actions. They turn the controller’s commands into physical movements. Available in forms like Hydraulic, Pneumatic, and Electrical, they produce movement in straight lines or circles. By following the controller’s orders, Actuators help control things like valves and motors. They make the necessary changes happen in the control system.
