# Control system
## MicroSim spec
- **Recommended sim type:** control system
- **Microsimmability score:** 88/100
- **Layout:** drawing region (canvas) on top; control region (sliders/buttons) below.
### Parameters (tunable controls)
- `Setpoint`
- `Controller gain`
- `Disturbance`
### What animates
A plant output tracks its setpoint and rejects disturbances as the controller gain changes.
### Learning objective
Show how a control loop drives a [[System|system]] toward a desired state.

## Concept summary
A control system manages, commands, directs, or regulates the behavior of other devices or systems using control loops. It can range from a single home heating controller using a thermostat controlling a domestic boiler to large industrial control systems which are used for controlling processes or machines.
## Build checklist
- [ ] Claim it: set `status: in-progress` + `lease` + `leased_at`
- [ ] Write the child page explaining the concept (tie it back to systems thinking)
- [ ] Finalize parameter ranges and defaults
- [ ] Implement the p5.js sketch (drawing + control regions)
- [ ] Add caption + the learning objective on the page
- [ ] Set `status: done`
## p5.js sketch
```javascript
// MicroSim: Control system
let controls = {};
function setup() {
// createCanvas(...); create sliders for the parameters above.
}
function draw() {
// background(...); read controls; render control system; respond live.
}
```
