Steer-by-Wire System Design Using Simulink
Langenwalter and Erkkinen [Lan04] described how to use Simulink to design an
automotive steer-by-wire system. The system uses electronic controls to trans-
late steering column turns to the wheels. Langenwalter and Erkkinen use a
model-based design methodology to successively refine the system from con-
cept to verified system.
A behavioral model of the system includes the physical plant—in this case,
the car—and a simple model of the control system. This behavioral model can
be simulated to determine that the car behaved properly while controlled by the
steer-by-wire algorithms. ...
