|
no feedback information on quality, therefore the process will continue with no interference |
|
Disadvantage of open-loop control system
|
Cannot detect or correct any errors
|
|
Application of open-loop control system

Basic processes e.g. a light switch
|
|
Closed-loop control systems
|
Utilise feedbback, to make decisions about changes to a process
|
|
Advantages of closed-loop control systems
|
Improved performance tracking throughout production process and early detection of faults that can be rectified
|
|
Applications of closed-loop control system |
More complex systems e.g. a light switch with a dimmer
