Lecture 1 - Introduction to Control Flashcards
vestibulo-ocular reflex (VOR)
eye movement reflex that stabilizes imagines on the retina during head movement
control theory + genetics =
systems biology
control theory has been applied to which fields?
- motor physiology - gene regulatory networks
define: plant
thing we want to control/influence
___ receives input and sense commands to the plant
controller
types of control
- open loop 2. feedback 3. internal feedback
open loop
input -> controller -> plant -> outcome
- controller receives no feedback
Another name for open-loop
ballistic control
Limitation of open-loop control
cannot recover from malfunctions or disturbances happening at the plant
Feedback control
Control system which monitors its own progress and adjusts its commands accordingly
Examples of feedback control:
- Mechanical
- Biological
- Heat seeking missile
- balance
What body parts do we use for balance/posture?
- Inner ears
- Vision
Limitation of feedback control
- disturbance is too great
- Delay around the loop
In feedback control, ____ send information about outcomes back to controller.
Sensors
Solution to feedback delay
Use plant models and internal feedback
