Open loop control, means that there is no feedback. A command is sent, but no confirmation that it has been received or executed or by how much.
traffic signal,blind person,
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 sensitivity of an open loop control system is always 1, it is due to no feedback involved in open loop.
A: By definition there is no control on a system in an open loop situation. simply . it has no feedback
The open loop system is simple and economicaleasier to constructstable
A cruise control is an example of a closed loop servo.
The difference between open loop and closed loop injection moulding is to do with the type of control system used. An open loop system changes the input signal relative to the pre-defined perameters of the system. A closed loop system uses a feedback signal ie it takes information from a point in the process usually the end and sends it back to the start where the system adjusts the input accordingly. To fully understand this I would suggest getting a good book on control theory. I use 'Modern Control Engineering' by Katsuhiko Ogata. Many people also use Richard Dorf but I find Ogata easier to follow. AuthorOgata, Katsuhiko.TitleModern control engineering / Katsuhiko Ogata.
no difference that's the difference
According to 'Modern Control Engineering' written by Katsuhiko Ogata, the ratio fo the feedback signal, H(s)C(s)to the actuating error signal (R(s)-B(s)) is called the open-loop transfer function. Here, H(s) is the transfer function of the feedback signal detector, C(s) is the output signal and R(s) is the setpoint signal.
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
Doing sex is an example of open loop so in this system u cannot control the amount of sperms entering your partner
