The sensitivity of an open loop control system is always 1, it is due to no feedback involved in open loop.
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.
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
Open Loop control Systems have input, then the input is processed by various components like amplifiers, filters etc, then final out stage.The main difference between open loop and closed loop systems is that in open loop systems there is no feedback.
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.
The Nyquist stability criterion, named after Harry Nyquist, provides a simple test for stability of a closed-loop control system by examining the open-loop system's Nyquist plot. Under many circumstances, stability of the closed-loop control system may be determined directly by computing the poles of the closed-loop transfer function. In contrast, the Nyquist stability criterion allows stability to be determined without computing the closed-loop poles
The open loop system is simple and economicaleasier to constructstable
A: By definition there is no control on a system in an open loop situation. simply . it has no feedback
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
closed loop system
yes
open loop
Doing sex is an example of open loop so in this system u cannot control the amount of sperms entering your partner
control action independent of the output or desired quantity
it is when a control loop is open and processing
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.
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.
Open loop (single cycle) involves a break requiring a restart, easily adapted to closed loop.
