Area 12
Control systems
Feedback wey dey keep system for di target
Control systems dey measure wetin machine dey do, compare am wit wetin e suppose do, and correct am, again and again. Dis feedback dey keep room for di correct temperature or tank for di correct water level.
Who e good for
Learners wey enjoy graphs and fine-tuning, and anybody wey don wonder how thermostat dey keep room warm.
Wetin you go learn
- Wetin be feedback: measure, compare, correct
- How sensors and controllers dey work togeda
- How PI or PID controller dey decide how strong e go react
- Why system fit overshoot or swing, and how to make am steady inside di learning model
Example experiments
-
Keep one virtual tank for one target water level by controlling one valve.
-
Tune one controller and watch weda di temperature go overshoot di target.
-
Switch feedback off and on, and compare how di system dey behave.
Tins wey you fit build
-
Thermostat for greenhouse
-
Water-level controller for tank
-
Motor wey dey hold steady speed
Dis examples dey show di kind work wey dey dis area. Di lessons wey dem go publish fit different.
Wetin di simulation simplify
- Di systems na simplified learning models: dem dey show di idea of control, no be di exact behaviour of real machine.
- Real sensors get noise and dem dey slow, and real machines get limits wey model fit leave out.
Every simulation dey simplify reality. To sabi how e dey do am na part of learning engineering.
How e connect to school subjects
Maths (graphs and rates), physics, computer science, technology
Connection to oda areas
Control systems dey build on top automation, sensors and electrical circuits, and dem dey keep robots, heating and water systems steady.
E good make you know
Your body dey use feedback too: wen you too hot, you go sweat to cool down, and wen cold catch you, you go shiver to warm up.
