The demo provides an overview of recent results in this area. In particular, it combines recent developments in various subproblems into a complete automotive control application package. This also demonstrates the capabilities and usefulness of Integrated System's CASE tools towards automotive control applications. The powertrain part contains the speed control and engine rpm control demos. The longitudinal dynamics of an automobile is modeled using systembuild.
Speed control is achieved by designing a sliding mode controller for the nonlinear powertrain model.
The suspension demo uses the interaction between systembuild and Xmath. Models are developed in systembuild which are used to design controllers in Xmath. This is possible as the models for suspension design are mostly linear. The suspension demo can serve as an example of hierarchical modeling usi ng systembuild. We use optimal control methods for design of automotive suspensions.
