Abstract
Through the last decades, vehicles have become more and more complex. As time passes, they are composed by even more electromechanical systems, which include many automotive control units. One essential part of a vehicle is the automotive suspension, responsible not only for supporting the weight of the vehicle itself and attenuating vibrations, but also for being an indicator of the overall performance of the car. Consequently, many studies have been performed throughout these years to improve the performance of automotive suspensions. One field of study that has gained great notoriety in this scenario is the usage of control systems to make it possible for the automotive suspension to adapt and perform in an optimized way according to the road profile characteristics, creating the so-called active suspensions. This work presents the development of an embedded LQR control strategy applied to an active suspension based on a quartercar model, used for improving the comfort of the passenger, as well as reducing suspension travel and improving vehicle driving, while maintaining good contact between tire and road. In order to validate such system, both Model in the Loop (MIL) and Hardware in the Loop (HIL) simulations are performed, with the latter one utilizing a low-cost HIL platform developed at the University of Brasilia. Thus, this works serves as validation for both the embedded control strategy developed and the HIL platform itself.
