Memory Aid
To remember the components of a control system, use the acronym REACT:
- R: Receptor (detects changes in the environment)
- E: Effector (carries out the response)
- A: Action (the effector carries out an action to reverse the effect of the change)
- C: Coordination Centre (interprets signals from the receptor and sends responses to the effector)
- T: Threshold (the level at which a response is triggered)
