Information
Electric Kettle: Model Calibration
Introduction
This is a model of an electric kettle used for heating water. The heating circuit is controlled by a thermostat and a timer.
In order to get the full experience of this example, you need the following:
- A desktop Wolfram Language product; a free trial download is available at www.wolfram.com/mathematica/trial/
- The ElectricKettle.nb notebook that came in the same bundle as this model
Parts of this example require the Wolfram Language. Open the accompanying notebook ElectricKettle.nb for those scenarios.
Model Calibration
Using Mathematica, fit the parameters for the resistor and the heat loss to measurement data.
Simulation Analysis
To simulate the system and see a plot of its behavior, follow the steps below:
- Click the
button in the top-right corner. - When the build is finished, click the Simulate button
.
A plot showing the behavior for the system can now be seen:
The control has a timer that keeps the temperature around 99 °C for 10 minutes.
