In the process of preventing rollover, the expected path of the driver to achieve better anti-rollover effect is often ignored, which may lead to the deviation of vehicle from the original path. Aiming at this problem, this paper considers both anti-rollover and path tracking performance, and proposes an integrated controller based on active steering and active braking. On the one hand, it can reduce the lateral acceleration and rollover risk by restraining the front wheel angle as tracking the driver’s expected path. On the other hand, through reasonably distributing the braking force of the four tires, it can offset the additional yaw moment caused by uneven distribution and reduce the impact on vehicle trajectory as the risk of rollover occurs. In addition, an improved index of rollover is put forward to give early warning to the future moment and to prevent rollover accident effectively. Simulation and hardware-in-the-loop test results show that the proposed integrated controller can ensure that the vehicle tracks the expected path well and achieves rollover prevention effectively.

Bu çalışmada, 1500 V DC beslemeli bir raylı sistemde cer gücünün meydana getirdiği gerilim düşümünün maksimum değeri Yapay Sinir Ağları (YSA) ve Destek Vektör Makineleri (DVM) yardımıyla belirlenmiştir. YSA ve DVM yöntemleriyle hatta oluşan gerilim düşümü işletmesel parametrelere bağlı olarak hesaplanmıştır. YSA ve DVM teknikleri açıklanarak elde edilen sonuçlar karşılaştırılmıştır. YSA modeli için levenberg marquardt (LM) algoritması kullanılmıştır. Levenberg-Marquardt algoritması yapay sinir ağlarının eğitiminde sağladığı hız ve kararlılık nedeni ile tercih edilmektedir. Raylı sistemlerde elektrifikasyon sistemi işletmesel verilere ve hat parametrelerine bağlı olarak tasarlanmaktadır. Elektrifikasyon sistemi oluşturulurken işletme esnasında cer gücünün gereksinimi olan minimum besleme gerilim değerinin sağlanması gerekmektedir. Cer gücü geriliminin en düşük değerini hatta oluşan gerilim düşümünün en yüksek değeri belirlemektedir. Bu değerin işletme sürekliliği için belirli limitler içinde tutulması gerekmektedir. Benzetim için tek yönlü ve çift yönlü beslenme durumlarına ait oluşturulan veriler incelenmiştir. Bu çalışma ile demiryolu elektrifikasyon sistemine ait cer gücü simülasyonuna ait sonuçlar yapay zeka yoluyla tahmin edilmektedir. Bu sayede sisteme ait değişkenler farklı olsa dahi tekrar tekrar benzetim yapılmasının önüne geçilmektedir. Tasarlanan sistem ile %95 üzeri başarı oranı elde edilmiştir.

“…However, when a short-circuit fault occurs in the traction network, or a short-circuit experiment, the amplitude of the shortcircuit current increases rapidly [7], and transient current pulses (TCP) will be generated. The large transient current propagates along the transmission line (TL), which will form a strong magnetic field and radio interference, thereby affecting electrical equipment through the cable [8][9][10][11]. Therefore, it is necessary to study the EMI of the transient electromagnetic field (TEMF) caused by the traction network short-circuit fault (TNSF) on the shielded cable terminal load.…”

The transient current pulse (TCP) caused by the traction network short-circuit fault (TNSF) will produce a high-strength transient electromagnetic field (TEMF). The electromagnetic field will interfere with nearby weak current equipment through the shielded cable. In this paper, a transient circuit model (TCM) for the short-circuit traction network is proposed to calculate the transient current. The short circuit is equivalent to a ring, and the TEMF transient electromagnetic field is calculated based on the magnetic dipole. The current response of the TEMF transient electromagnetic field on the shielded cable is deduced based on the transmission line theory and verified by experiments. The electromagnetic interference (EMI) of a TEMF transient electromagnetic field to the shielded cable terminal load were was studied under various incidence angles, azimuth angles, and polarization angles. The results demonstrate that the greater the incident angle and azimuth angle, the greater the EMI on the terminal load. The horizontal distance between the shielded cable head and the short-circuit point should be greater than 6 m, and the incident angle should be greater than 45∘. This method can provide a theoretical basis for the electromagnetic compatibility research of traction power supply systems and their nearby weak current equipment.
