ABSTRACT
Lateral control in autonomous parking system, which is always at low speed, simultaneously requiring very small following error, is a difficult problem to resolve.  To address this problem, this paper introduces the Fractional order controller. What’s more, to address the parameters tuning problem in design of the controller, an improved genetic algorithm is adopted. With the proposed method, simulation and real vehicle experiments are carried out. Results show that fractional order controller can manage the vehicle to follow the planned trajectory preciously and that stably and robustly in autonomous parking process, which is at low speed.
