# Ludwig von Bertalanffy
## MicroSim spec
- **Recommended sim type:** control-loop
- **Microsimmability score:** 36/100
- **Layout:** drawing region (canvas) on top; control region (sliders/buttons) below.
### Parameters (tunable controls)
- `Gain Kp` (0–10, proportional strength)
- `Setpoint` (target value the loop drives toward)
- `Disturbance` (0–1, external upset injected into the plant)
### What animates
A block-diagram loop drives a plant toward the setpoint; the error [[Signal|signal]] and the corrective response update live as gain and disturbance change.
### Learning objective
See how loop gain trades responsiveness against overshoot and stability.

## Concept summary
Karl Ludwig von Bertalanffy (19 September 1901 – 12 June 1972) was an Austrian biologist known as one of the founders of general systems theory (GST). This is an interdisciplinary practice that describes systems with interacting components, applicable to biology, [[Cybernetics|cybernetics]] and other fields.
## Build checklist
- [ ] Claim it: set `status: in-progress` + `lease` + `leased_at`
- [ ] Write the child page explaining the concept (tie it back to systems engineering)
- [ ] 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: Ludwig von Bertalanffy
let controls = {};
function setup() {
// createCanvas(...); create sliders for the parameters above.
}
function draw() {
// background(...); read controls; render control-loop; respond live.
}
```
