# Comparison of system dynamics software
## MicroSim spec
- **Recommended sim type:** control-loop
- **Microsimmability score:** 30/100
- **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
This is a comparison of various aspects of software offering [[System_dynamics|system dynamics]] features:.
## 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: Comparison of system dynamics software
let controls = {};
function setup() {
// createCanvas(...); create sliders for the parameters above.
}
function draw() {
// background(...); read controls; render control-loop; respond live.
}
```
