# Qian Xuesen
## MicroSim spec
- **Recommended sim type:** control-loop
- **Microsimmability score:** 50/100
- **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.

> Qian Xuesen (Chinese: 钱学森; 11 December 1911 – 31 October 2009; also spelled as Tsien Hsue-shen) was a Chinese aerospace engineer and cyberneticist who made significant contributions to the field of aerodynamics and established engineering cybernetics. He achieved recognition as one of America's leading experts in rockets and high-speed flight theory prior to his returning to China in 1955.[1] ([Wikipedia](https://en.wikipedia.org/wiki/Qian_Xuesen))

## 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: Qian Xuesen
let controls = {};
function setup() {
// createCanvas(...); create sliders for the parameters above.
}
function draw() {
// background(...); read controls; render control-loop; respond live.
}
```
