Is washing machine is open loop or closed control system and why?
closed loop system
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 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.
Disadvantages of Closed Loop control?
A closed loop system for the purpose of feeding back the output signal to the input side requires sophisticated sensors, which make this scheme expensive to implement. Initial tuning of the system is also difficult(feedback serves the purpose of fine tuning).
Is automobile cruise control open or closed loop?
A cruise control is an example of a closed loop servo.
What is the difference between finite open loop gain and closed loop gain?
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)]
Is washing machine is open loop or closed control system and why?
closed loop system
What is the physical significance of infinite open loop voltage gain of an ideal operational amplifier?
Distortion is estimated as closed loop gain divided by open loop gain. If the open loop gain approaches infinity, distortion approaches zero.
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
Why open loop gain of op-amp is very high?
A; An ideal op amp should have infinite open loop gain so when the loop is closed with negative feedback it will be stable
Is the gain same for the same system in open loop and close loop?
no.
Is Computerized Numerical Control machine open loop system or closed loop system?
yes
Formulas of a unity-feedback loop?
The formulas of a unity-feedback loop are: Closed-loop transfer function: This is the ratio of the output of the system to its input in the closed-loop configuration. It is calculated by dividing the open-loop transfer function by (1 + open-loop transfer function). Closed-loop gain: This is the gain of the system in the closed-loop configuration and represents the amplification of the input signal in the system. It is calculated by multiplying the open-loop gain by (1 + open-loop gain). Closed-loop bandwidth: This is the frequency range over which the system can effectively respond to input signals in the closed-loop configuration. It is usually determined by the pole locations in the system's transfer function.
Do sharks have an open or closed circulatory system?
Brown bear have a close circulation system
Is Human body open or closed loop control system?
open (in terms of thermo chemistry) ! It cannot be proved with science yet! BUT WHEN ONE TOUCHES SOMEONE, LOOKS THEM IN THE EYE, so forth one feels the exchange of energy(emotions). they are being effected by the surrounding !
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
