First-Order-Delay-Controlled Slip-Angular Frequency for the Dynamic Performance of an Indirect-Field-Orientation-Controlled Induction Motor-Driving Inertial Load

Autor: Masaki Nagataki, Keiichiro Kondo, Osamu Yamazaki, Kazuaki Yuki

Publikováno v: IEEE Open Journal of Industry Applications, Vol 4, Pp 160-177 (2023)

Sophisticated torque-current control is required in inertial load-drive applications, such as in electric vehicles and electric railway vehicles, over a wide speed range. However, the conventional indirect-field-orientation control (FOC) lacks the cu

Online Auto-Tuning Method in Field-Orientation-Controlled Induction Motor Driving Inertial Load

Autor: Masaki Nagataki, Keiichiro Kondo, Osamu Yamazaki, Kazuaki Yuki, Yosuke Nakazawa

Publikováno v: IEEE Open Journal of Industry Applications, Vol 3, Pp 125-140 (2022)

Feed-forward current control, which employs a single-pulse mode of inverters over a wide speed range, is applied in inertial load drive applications such as electric vehicles and electric railway vehicles. It is necessary to identify both primary and

Energy-Management Method to Reduce the Capacity of Lithium-Ion Batteries in Hybrid-Voltage-Source Three-Level Inverter for DC-Electrified Railway Vehicles

Autor: Tadashi Mizobuchi, Keiichiro Kondo, Yosuke Dairaku, Takeshi Shinomiya, Katsumi Ishikawa

Publikováno v: IEEE Open Journal of Industry Applications, Vol 3, Pp 41-55 (2022)

The hybrid-voltage-source three-level inverter is a traction circuit system aimed at realizing energy savings with lithium-ion batteries for direct-current-electrified railway vehicles. However, this system has the limitation of being unable to freel

Advantages and technical issues of regenerative brake method at all over the speed range

Autor: Febry Pandu WIJAYA, Sho WATANABE, Tatsuhito SAITO, Hiroyasu KOBAYASHI, Keiichiro KONDO

Publikováno v: Mechanical Engineering Journal, Vol 4, Iss 1, Pp 16-00473-16-00473 (2016)

In this paper, the authors propose “regenerative brake notch” method which follows the maximum regenerative brake force according to the vehicle speed. This specially designed brake force reference selected by the train driver aims at saving the
