Special Issue Information

Dear Colleagues,

Recently, electric transportation has become one of the most attractive research topics, exploiting continuous progress in the application of new materials together with advances in the design and control development of electric machines. Better efficiency, a smaller environmental footprint, and the replacement of petroleum or comparable fuels as the primary energy source are the development directions for electric transportation. In this regard, electric vehicles are more energy-efficient than conventional vehicles that use internal combustion engines. Advances in machine design, power electronic switches, and electric drive controls are necessary for electric vehicles to succeed in meeting the increasingly demanding standards of contemporary transportation systems. The recent developments in electric drives and machines will significantly influence the development of the next generation of electrified transport systems.

This Special Issue will gather and present the latest advances in electric machines and associated drives for the more electric transportation sector. Topics of interest for this Special Issue include, but are not limited to, the following:

  • All-electric machines, drives, and converters/inverters;
  • Design and control of electric vehicle drives;
  • Novel topologies and materials (magnetic, electronic, and structural, e.g., light-weighting, low-cost, non-rare-earth e-machine);
  • Drive configurations;
  • Component- and system-level optimizations;
  • Control system topologies;
  • Hybrid hydrogen powertrain;
  • Reliability and condition monitoring of electric drive systems.

This research addresses the issues of weak anti-disturbance ability, fast response, and incompatibility of overshoot in the control process of brushless DC motors (BLDCs). A six-step commutation control method based on second-order active disturbance rejection control (ADRC) is derived following the analysis of the BLDC model and the mathematical model of ADRC. A control model of the BLDC using both PI and ADRC is constructed. Detailed comparative and quantitative analyses of the simulation results using PI and ADRC are conducted, focusing on the anti-load disturbance capabilities using the integrated square error (ISE), integrated time square error (ITSE), integrated absolute error (IAE), and integrated time absolute error (ITAE). Experimental testing on the STM32F4 controller is also carried out, analyzing four error integral criteria in depth. The results indicate that both the ADRC and PI control modes can track the target signal without overshooting, demonstrating strong anti-load disturbance ability and robustness at varying working speeds. In the BLDC control system, using the ADRC control method can achieve fast and non-overshoot tracking of target signals compared to the PI control method, and ADRC has stronger resistance to load disturbances.

Torque fluctuations in drivetrains are the result of dynamic excitations and can be unfavorable for the lifetime of the system. Passive ripple suppression methods exist, such as torsional dampers and flywheels, which are often bulky and not always desired. Alternatively, performant active control methods exist; however, their applicability to certain drivetrains is not covered. Therefore, this paper focuses on active control from a mechanical perspective, more specifically, drivetrain dynamics impacting active control effectiveness. A quasi-resonant controller is implemented as an active control method, and its performance and robustness are proven both in simulation on a 3-DOF mechanical model and experimentally at different excitation frequencies. The tests show that active control effectiveness is highly drivetrain-dependent. In particular, the propagation of the torque oscillation is influenced by the elastic filtering properties of the drivetrain, and the speed ripple depends on the inertial attenuation of the drivetrain. High-stiffness, low-inertia drivetrains benefit best from active control for ripple suppression because the inertial attenuation is limited, while high-stiffness elements increase the mechanical bandwidth before dynamic decoupling happens between the inertias of interest. Active control serves as a viable alternative for speed ripple reduction when drivetrain compactness is key, instead of the current passive solutions. Full article
