What are automatic controls in electrical engineering???

In electrical engineering, automatic controls deals with a system that is capable of operating without input from a human. Though this may sound simple, it is quite an effort. It requires the concept of feedback.





Feedback is a closed loop system in which the actions of the system are used by the system to determine the next operation. For example, the system goes off and does something. Some form or type of sensor provides information back into the system's processing unit. From that information, the processing unit has to make decisions, which in term, affects the actions of the system...(Almost the the concept of the chicken and egg)





The problem with feedback loops is the difficulty of processing enough data so that the system can perform its function without being bogged down in the processing of the data.





If it was THAT simple, we would not have to steer and control our cars. We should be able to hop in and let the car do the rest.What are automatic controls in electrical engineering???
anything that monitors and turns on equipment by itselfWhat are automatic controls in electrical engineering???
these are devices attached to a process and act by giving orders under certain conditions. they are automatic for that reason and because they protect and manipulate the process in different conditions.
