Conoscenze e abilità da conseguire

The course deals with dynamics and control of electric vehicles and with the compliant implementation of control policies on the programmable electronics systems that supervise the operation of the vehicle. The students will learn to describe a vehicle as a 3-D dynamic system, design optimal control strategies, and implement such strategies on the programmable electronics systems that supervise the operation of the vehicle, with focus on compliance with safety and reliability standards.
