Stateflow

Exploring a Real-World Stateflow Application

The modeling of a fault tolerant fuel control system demonstrates how Simulink and Stateflow may be used to efficiently model hybrid systems containing both continuous dynamics and complex logical behavior. Elements in the model containing time domain based dynamic behavior are modeled in Simulink, while changes in control configuration are implemented in Stateflow.

The model described 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. This section describes how Stateflow is used to implement the supervisory logic control system dealing with the sensor failures.
