Abstract:
The design problem of optimal comfort-oriented semi-active suspension has been addressed with different standard techniques which failed to come out with an optimal strategy because the system is hard non-linear and the solution is too complex to be found analytically. In this work, we aimed at solving such complex problem by applying Batch Reinforcement Learning (BRL), that is an artificial intelligence technique that approximates the solution of optimal control problems without knowing the system dynamics. Recently, a quasi optimal strategy for semi-active suspension has been designed and proposed: the Mixed SH-ADD algorithm, which the strategy designed in this paper is compared to. We show that an accurately tuned BRL provides a policy able to guarantee the overall best performance.
