Feedback from the output to the input will provide stability and control. It is desirable to havemaximum open loop gain but without proper feedback it will be probably totally unstable

What is sensitivity of open loop control system?
The sensitivity of an open loop control system is always 1, it is due to no feedback involved in open loop.
What are the disadvantages of closed loop systems?
its costly than open loop system and bulky, too.
How are input and feedback parts of a system are related?
They are either in closed or in open loop system
What is the definition of closed loop control system?
A closed loop control system is a set of mechanical or electronic devices that automatically regulates a process variable to a desired state or set point without human interaction. Closed loop control systems contrast with open loop control systems, which require manual input.
Open loop and closed loop systems?
Very generally, a closed-loop system will have some form of feedback that regulates the system behavior, whereas an open-loop system does not have this feedback. As a simple example, imagine you driving a car on a freeway: your car enters at 50 MPH and you want to be driving at 65 MPH. You know that if you depress the pedal at a certain degree for a certain amount of time, you will eventually accelerate the car to 65 MPH. In an open-loop system, you would have to make the best guess for the angle and amount of time you need to depress the pedal. In a closed-loop system, you are watching your odometer in order to see that you've actually increased your speed to 67 MPH and need to lay off the gas a bit. More importantly, if your car encounters a hill your closed-loop system will be able to recognize the fact that you require more acceleration to maintain your speed, whereas your open-loop system might slow down a lot. It should be clear from this example that closed-loop systems are in general more robust to changes in the system state that aren't considered in your model.
Examples of the open loop system?
The system without feedback is known as open loop system. The examples of the open loop system are bread toaster, oven ,washing machine. The open loop systems are inaccurate & less complex.
What is sensitivity of open loop control system?
The sensitivity of an open loop control system is always 1, it is due to no feedback involved in open loop.
Advantages of open loop control system?
The open loop system is simple and economicaleasier to constructstable
Why closed loop control system is much stable than open loop control system?
A Closed loop system basically will have a feedback which enables the rectification of the error in the main process,whereas it is not possible in an open loop system
Is washing machine is open loop or closed control system and why?
closed loop system
Is the gain same for the same system in open loop and close loop?
no.
Open loop and close loop system in injection moluld machine?
loop checking is perform before cable termination..the difference between a close loop and open loop is,tha close loop has a feedback while the open loop has not.
Is Computerized Numerical Control machine open loop system or closed loop system?
yes
What is an open loop in control systems?
A: By definition there is no control on a system in an open loop situation. simply . it has no feedback
Do amphibians have a single loop circulatory system?
no they have double loop circulatory system but the difference is that they have single ventricle.
Is street light system is closed loop or open loop?
An open loop traffic signal just cycles on a schedule and has no "knowledge" of traffic patterns or current traffic. A closed loop system would have sensors letting it know when traffic was present and a controller that would make decisions based on the traffic conditions.
Is the gain same for same system in open loop and closed loop?
A: DEFINITELY NOT Open loop is defined as no feedback. any kind of negative feedback will reduce the gain
