Modeling of Automatic Transmission Controller
In this video demo, SimDriveline™ and Stateflow are used together to model an automatic transmission. SimDriveline is used to model the powertrain plant while Stateflow is used to model the logic of the controller that instructs the transmission to either shift up or down.

|
Automotive Powertrain Control System
This video demonstration, presented in several short segments, illustrates Model-Based Design for an automotive powertrain controller. Stateflow is shown in conjunction with Simulink® Verification and Validation™ to illustrate how to analyze the amount of model coverage provided by a given set of tests.

Automotive Power Window System
In this case study we model an automotive passenger power window system using Model-Based Design with Simulink, Stateflow, SimMechanics™, and SimPowerSystems™ . We will design the controller from a set of requirements, build a plant model to test the controller, and finally verify that the controller meets the requirements.

Modeling Fault Management Control Logic in an Aircraft Elevator Control System
 In this demo, we use Model-Based Design to design a fault detection, isolation, and recovery (FDIR) application for a pair of aircraft elevators with redundant actuators.

|
|
Modeling a Launch Abort System
In this video demonstration, we model a launch abort system. An aircraft is launched into outer space. If an anomaly or fault occurs during the launch, the operation is aborted, and the aircraft is sent back down to Earth.

Spacecraft Automated Landing System
In this video demo, we model an automatic landing system for the HL-20, a spacecraft based on a specification from NASA. Stateflow is used to model the fault management system of the vehicle.

Designing an Aircraft Elevator Control System
In this case study, we use Model-Based Design with Simulink, Stateflow, and Simulink Verification and Validation to design a fault detection, isolation, and recovery (FDIR) application for a pair of aircraft elevators with redundant actuators. The system is modeled from a set of requirements. We then use requirements-based testing in order to verify that these requirements have been met.
