Open loop system

Basic concept for loop system

Open loop system (open loop controller)

We know open loop system as non feedback system. Because this is a type that computes input into a system using the current stae of the system. open-loop controller characteristic is that it does not use feedback to determine the output has achieved the desired goal that we want to get. This mean that the system does not observe the output of the processes that it is controlling. The actual open-loop system can not engage in machine learning which mean it cannot correct any errors that it could make. It also may not compensate for disturbances in the system.

Close loop system ( control)

A Closed-loop Control System, is the opposite of the open loop system. Which is the system that has a  feedback control system  and uses the concept of an open loop system as its forward path. However there is another path added between the output and its input. So basically some portion goes out of the system and some still recycle back. In Biology it is like the Air or kidney system, when waste is filter out of body but fluids are recycle back in to body.In addition we know that closed d-loop systems are designed to automatically achieve and maintain the desired output condition by comparing it with the actual condition. It does this by generating an error signal which is the difference between the output and the reference input. This is automatic system that check the error of the out put the report it back then fix it.
