Yasser Shoukry, Mohamed Watheq El-Kharashi, Sherif Hammad · IEEE Embedded Systems Letters · 2010
Safety critical automotive systems require tight real-time constraints. This letter presents a case study for embedded implementation of a model predictive controller (MPC) used to control an automotive active suspension system. It proposes a special purpose coprocessor for solving the online mathematical optimization needed by the controller, while maintaining real-time constraints imposed by system dynamics. Mathematical formulation for the optimum usage of hardware resources is provided and verified for its applicability on a proposed platform.
