Foxboro FBM242 Input channel powering and grounding module

Description

Open loop control system refers to a system where the output of the controlled object (controlled quantity) has no effect on the output of the controller. In this control system, it does not rely on sending the controlled quantity back to form any closed-loop loop. The characteristic of a closed loop control system is that the output (controlled quantity) of the controlled object in the system will be sent back to affect the output of the controller, forming one or more closed loops. A closed-loop control system has both positive and negative feedback. If the feedback signal is opposite to the given value signal of the system, it is called negative feedback. If the polarity is the same, it is called positive feedback.

Generally, closed-loop control systems use negative feedback, also known as negative feedback control systems. There are many examples of closed-loop control systems. For example, a person is a closed-loop control system with negative feedback, and the eyes are sensors that act as feedback. The human system can make various correct actions through continuous correction. If there are no eyes, there is no feedback loop, and it becomes an open loop control system. For example, when a truly fully automatic washing machine has the ability to continuously check whether the clothes are clean and automatically cut off the power after washing, it is a closed-loop control system.
