When free water remains, the pot stays near 100\u00b0C; once the water is gone, the temperature rises sharply, providing a natural signal that cooking is complete.<\/p>\n<p>That makes it an excellent home-appliance example for <a href=\"https:\/\/www.ansys.com\/products\/embedded-software\/ansys-scade-one\">Scade One<\/a>. The behavior maps naturally to state machines, while dataflow (the graphical wiring to compute values at every cycle) handles the numerical and timing logic: this keeps the overall design structured and easy to understand. At the same time, Scade One brings the industrial-grade rigor inherited from safety-critical applications in SCADE, helping raise model quality from the start.<\/p>\n<p>In this post, we build a rice cooker controller, connect it to a simplified plant model, and simulate the closed-loop behavior with graphical panels. The goal is not to create a perfect kitchen-ready model, but rather a first prototype within a few hours to show how Scade One helps organize the logic, validate behavior early, and make the design easy to explore. By the end, we will see how Scade One gets a controller from concept to interactive simulation in a single environment.<\/p>\n<p>Let&#8217;s get started.<\/p>\n<h4  id=\"%F0%9F%8D%9A-WHAT-MAKES-A-RICE-COOKER-INTERESTING-TO-MODEL\">\ud83c\udf5a What makes a rice cooker interesting to model?<\/h4>\n<p>At first glance, a rice cooker looks like a very basic appliance. However, it highlights several useful engineering ideas in a single model:<\/p>\n<ul>\n<li>clear operating modes such as idle, delayed start, cooking, and keep-warm<\/li>\n<li>a physical process with a visible phase change around boiling that acts as a signal to stop cooking<\/li>\n<li>user inputs and safety conditions, such as opening the lid or cancelling the program<\/li>\n<li>temperature regulation for soaking and keep-warm phases<\/li>\n<\/ul>\n<p>To stop cooking, a mechanical rice cooker uses Curie<a href=\"https:\/\/innovationspace.ansys.com\/knowledge\/wp-content\/uploads\/sites\/4\/2026\/04\/scade-067-curry.gif\">&#8216;<\/a>s law: a metal piece loses its ability to be magnetized above 100\u00b0C, releasing a spring that cuts the power. Modern rice cookers use sensors (temperature, steam, etc.) and a digital controller to regulate power for optimal cooking.<\/p>\n<h4  id=\"%F0%9F%8E%AE-THE-CONTROLLER-MODEL-IN-SCADE-ONE\">\ud83c\udfae The controller model in Scade One<\/h4>\n<p>The controller reads the pot temperature (via a sensor), button inputs, and a lid-open sensor. It then computes three main outputs:<\/p>\n<ul>\n<li>heater power, as a percentage of the cooker nominal power<\/li>\n<li>text to display on a small screen<\/li>\n<li>LED color to indicate the current mode<\/li>\n<\/ul>\n<p>This logic fits Scade One well because the high-level behavior is best expressed as a state machine (capturing discrete operating modes and the transitions between them), while the numerical parts are naturally expressed with dataflow.<\/p>\n<p>At the top level, the controller is organized into five states:<\/p>\n<ul>\n<li><code>Idle<\/code>: wait for input<\/li>\n<li><code>SetDelay<\/code>: let the user configure the delayed start<\/li>\n<li><code>DelayedCooking<\/code>: count down to the start time<\/li>\n<li><code>Cooking<\/code>: handle the actual cooking sequence<\/li>\n<li><code>KeepWarm<\/code>: maintain the serving temperature after cooking completion<\/li>\n<\/ul>\n<p style=\"text-align: center\">\n    <img decoding=\"async\" src=\"https:\/\/innovationspace.ansys.com\/knowledge\/wp-content\/uploads\/sites\/4\/2026\/04\/scade-067-high-level-controller-1.png\" style=\"max-height: 500px !important\" \/><br \/>\n    <em>Figure 1: High-Level controller states<\/em>\n<\/p>\n<p>This highlights one practical strength of Scade One and model-based software development in general: instead of having a long sequence of conditional blocks, the operating modes are very explicit and easy to check in simulation.<\/p>\n<h4  id=\"%F0%9F%A7%91%F0%9F%8D%B3-GOING-INTO-THE-COOKING-MODE\">\ud83e\uddd1\u200d\ud83c\udf73 Going into the cooking mode<\/h4>\n<p>The <code>Cooking<\/code> mode is the most interesting part of the model.

On top of that, nested state machines with the possibility to hide state content (i.e. detached diagrams) give the possibility to have a clear hierarchy of the sequencing.<\/p>\n<p>Moreover, we can easily implement the closed-loop temperature control for the two phases requiring it:<\/p>\n<ul>\n<li><code>WaterAbsorption<\/code>, which keeps the temperature at 45\u00b0C for a configured soaking time<\/li>\n<li><code>KeepWarm<\/code> (the next top-level state), which regulates the pot around 65\u00b0C to avoid bacteria multiplication (under 60\u00b0C) or drying out (above 80\u00b0C)<\/li>\n<\/ul>\n<p>For both, a PI controller (Proportional Integral) with anti-windup is sufficient. The implementation reuses an example provided in the Scade One installation.
