# Industrial process control
## MicroSim spec
- **Recommended sim type:** time-series controller
- **Microsimmability score:** 90/100
- **Layout:** drawing region (canvas) on top; control region (sliders/buttons) below.
### Parameters (tunable controls)
- `Proportional gain Kp - 0 to 10`
- `Integral time Ti - 1 to 100 s`
- `Disturbance step - 0 to 100 %`
### What animates
A controlled variable tracks a setpoint over time while the PID controller rejects an injected disturbance; raising the gain speeds response but can drive visible [[Oscillation|oscillation]] or instability.
### Learning objective
See how controller tuning trades response speed against stability when rejecting a disturbance.

## Concept summary
Industrial process control uses sensors, controllers, and final elements to hold process variables (temperature, level, flow, pressure) at setpoint despite disturbances.
## Build checklist
- [ ] Claim it: set `status: in-progress` + `lease` + `leased_at`
- [ ] Write the child page explaining the concept (tie it back to process 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: Industrial process control
let controls = {};
function setup() {
// createCanvas(...); create sliders for the parameters above.
}
function draw() {
// background(...); read controls; render time-series controller; respond live.
}
```
