Control Simulations with Interactive Displays

Build dashboard for model, interactively tune parameter values, and monitor signal values during simulation

Create an interactive dashboard for your model using a variety of controls and displays available in the Dashboard library and the Customizable Blocks library.

Controls connect to variables and block parameters in your model, providing an interface for you to tune values during simulation.
Displays connect to signals and display the signal value during simulation.

To design custom dashboard blocks that look like controls and displays in your real system, choose blocks from the Customizable Blocks library. For example, you can create a photorealistic model of the speedometer in a real vehicle.

You can model real-life dashboards and control panels by adding blocks from the Dashboard library and the Customizable Blocks library to Simulink^® panels. Panels float above the canvas, can be moved to any location over the canvas, and can be minimized when you want to work on the model underneath them. Panels can have multiple tabs, so that you can organize your dashboard blocks into different groups.

Featured Examples

Model a Fault-Tolerant Fuel Control System

Combine Stateflow® with Simulink® to efficiently model hybrid systems. This type of modeling is particularly useful for systems that have numerous possible operational modes based on discrete events. Traditional signal flow is handled in Simulink while changes in control configuration are implemented in Stateflow. The model described below represents a fuel control system for a gasoline engine. The system is highly robust in that individual sensor failures are detected and the control system is dynamically reconfigured for uninterrupted operation.

Create a Realistic Dashboard Using the Circular Gauge Block

Use the Custom Gauge and MultiStateImage blocks to create a realistic dashboard for your model.

Create Dashboard Panel for Climate Control System

Create a climate control screen for an automotive infotainment system, modeled as a dashboard panel. You can use panels to model and test the user interface of a real system. To model displays and controls on the panel, such as gauges, lamps, knobs, buttons, and switches, you can promote dashboard blocks to the panel. Dashboard blocks are blocks from the Dashboard library, the Customizable Blocks library, and the Aerospace Blockset™ Flight Instruments library.

Open Model

Control a Parameter Value with Callback Button Blocks

Models control of a system that consists of two masses attached on either side of a spring.

Open Model

Two Cylinder Model with Load Constraints

Model a rigid rod supporting a large mass interconnecting two hydraulic actuators. The model eliminates the springs as it applies the piston forces directly to the load. These forces balance the gravitational force and result in both linear and rotational displacement.
