Control Simulations with Interactive Displays

Build a dashboard for your model, interactively control tunable parameter values and monitor signal values during simulation

Create an interactive display of controls and displays within your model diagram using blocks from the Dashboard library. Connect block parameters to control blocks (knobs, buttons, and switches) and signals to displays blocks (scopes and gauges).

Featured Examples

Modeling 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.

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.

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.
