VHDL-AMS Based Control Design for Automotive Systems 2007-01-1638
This paper deals with a virtual prototyping study, using VHDL-AMS language to model an automotive subsystem and to implement its control scheme. The automotive subsystem under study here is a control system for reference input wheel slip tracking. The control objective is to track a reference input wheel slip. A variable structure sliding mode controller is used to provide robust control of uncertain, often nonlinear, dynamical automotive systems. In this study, the main components of this control system, including the wheel dynamics, sensors, and control logic, are implemented in VHDL-ASM and the complete system is simulated in Simplorer®.
