OPen loop and close loop system Flashcards
(20 cards)
What is a key characteristic of open loop systems?
Do not have a feedback loop.
What is a key characteristic of closed loop systems?
Have at least one feedback loop.
What is feedback in control systems?
Where the output signal from a system becomes an input signal to the same system.
Which type of systems are more robust?
Closed loop systems.
Which type of systems are extremely accurate?
Closed loop systems.
What is an advantage of open loop systems in terms of design?
Less complicated and easier to design and maintain.
What is a cost-related advantage of open loop systems?
Less costly to produce due to fewer components.
Name a typical application of open loop systems.
Simple timer and latching systems.
Name another typical application of open loop systems.
Simple electronic counters.
Name a typical application of closed loop systems.
Temperature control and heating systems.
Name another typical application of closed loop systems.
Automatic security lighting systems.
Name yet another typical application of closed loop systems.
Robotic arms and/or vehicles.
What is a transfer function?
A mathematical representation of the contents of each block within a systems diagram.
What does the summing point produce?
The algebraic sum of the reference input signal and feedback signal.
Fill in the blank: Closed loop systems are _______.
more robust.
Fill in the blank: Open loop systems are _______ and therefore easier to design and maintain.
less complicated.
True or False: Closed loop systems are less likely to be affected by external disturbances.
True.
What is the output signal in a control system denoted as?
C(s).
What is the error signal in a control system denoted as?
E(s).
What are the reference input signal and feedback signal denoted as?
R(s) and B(s).
