cheaper than closed loop
open loop
turn the switch you assume the light is on
closed loop
turn the switch observe the current observe the light level...
can predict how much below optimal the performance is and predict when total failure will occur

An open loop system is simple and straightforward, requiring fewer physical or logical connections as the closed loop design. It lacks the feedback offered by closed loop designs. As such, it is often considered inferior to a closed loop design.
A closed loop design assures the initiator that the signal has not only been transmitted but also received. However, this often creates a false sense of security, as the semantics of a feedback signal may be ambiguous. For example, a light might feed back it's on or off signal regardless of the actual state of the luminaire, while a more sophisticated design might sample light levels and thus drive the feedback based on the real state of the luminaire. For another example, consider a closed loop multicast design where one controller (switch) drives multiple actuators (lights). Does the presence of a feedback signal indicate that at least one, or that all, lights assume the required state?
In summary, a closed loop design is generally superior and desirable, provided that the behaviour of this particular closed loop system is well known. A closed loop system without such detailed knowledge does not generally offer higher reliability, but requires typically twice the cost in physical or logical connections.
Well, In open loop as there is no feedback so it is less prone to oscillatiory response where as in closed loop, as feed back is there so if sensitivity is high, oscillations are always there hence less stable response.
hope it helps !!
Open loop is when the control system responds to the environment. For instance, a furnace would use a thermostat to regulate the temperature of a building. A closed loop would be if the thermostat were replaced with a switch. Then, a human would need to work the switch and keep the temperature within a good range.
Stability and simplicity in design
The sensitivity of an open loop control system is always 1, it is due to no feedback involved in open loop.
Distortion is estimated as closed loop gain divided by open loop gain. If the open loop gain approaches infinity, distortion approaches zero.
It depends. Which is more corrupt? -- An open loop or a closed loop? Whichever one is more corrupt, selfish, and greedy, then that is the one that befits attorneys.
Yes i can anwer it.
The two types of looping include the closed loop and the open loop.There is the count loop, the conditional loop and the unconditional loop.
The open loop system is simple and economicaleasier to constructstable
Doing sex is an example of open loop so in this system u cannot control the amount of sperms entering your partner
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.
it is when a control loop is open and processing
The sensitivity of an open loop control system is always 1, it is due to no feedback involved in open loop.
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.
In a closed loop system the gain without the feed back loop being closed is called open loop gain!!! e.g if forward gain is "A" and feed back factor is "B" then open loop gain is "AB" and closed loop gain will be [A/(A+B)]
Closed
A: By definition there is no control on a system in an open loop situation. simply . it has no feedback
Distortion is estimated as closed loop gain divided by open loop gain. If the open loop gain approaches infinity, distortion approaches zero.
no.
