Aiming to the torsional vibration destabilization phenomenon of the wheel-side transmission system direct-driven by the high-power motor, the system torsional vibration bifurcation characteristics and control strategy are analyzed. Through defining the system electromechanical coupling relationship between the electrical link and the mechanical link, the dynamic model of the wheel-side direct-driven transmission system is constructed. Then, based on the Routh–Hurwitz stability criterion, the system Hopf bifurcation characteristics caused by the change of the wheel-ground friction during driving are revealed. Furthermore, with the nonlinear feedback controller and the Washout filter combined, the system torsional vibration stabilization controller is constructed by introducing the system torsional vibration signals into the motor control voltage. The results show that the linear part of the torsional vibration stabilization controller can effectively change the system stability region, as well as the cubic nonlinear part of the torsional vibration stabilization controller can control the stability of the system bifurcation points and suppress the limit cycle amplitude. The research results can provide theoretical basis and technical support for the performance improvement and integrated application of the wheel-side direct-driven transmission system in the electric bus.

This article intends designing and implementing a hysteresis current controller for the energy management system within an electric traction to maintain the output voltage in a certain interval whatever the disturbances to the system. The energy management system within an electric traction encompasses a battery functioning as a fuel cell within the primary energy source, an ultracapacitor considered as an auxiliary source and two direct current to direct current converters renowned as boost and buck/boost converters, whose modeling is constantly contemplated as a very difficult task. As a matter of fact, these converters are designed as switching circuits with a prevalent change of structures, which makes them strongly nonlinear. Thereby, they can be assumed as hybrid dynamical systems whose continuous parts are especially characterized by electrical magnitudes, namely, the currents and voltages in the converters, and whose discrete part is illustrated by the high-frequency switching metal–oxide–semiconductor field-effect transistor which demands faster control mechanisms to ensure proper regulation of the output voltage of two direct current to direct current converters. The validity and effectiveness strategy control of the energy management system are highlighted by numerical simulation as well as by experimental implementation on the DSPACE1104 R&D Controller Board.

“…Szolc et al [23] researched the dynamic electromechanical coupling effects in machine drive systems driven by asynchronous motors, and the electromagnetic stiffness and damping coefficients of the interaction between motor and mechanical system were determined by means of the analytical method. Ju et al [24] constructed the global electromechanicalcoupling dynamic models for the main transmission system of the scraper conveyor, and the Hopf bifurcation characteristic is analyzed, which was caused by sliding friction. In view of the above mentioned, Hopf bifurcation is a significant factor affecting the stability of the electromechanical coupling transmission system.…”

The nonlinear torsional vibration and instability oscillation caused by nonlinear damping in the shearer electromechanical coupling cutting transmission system in shearer driven by the permanent magnet synchronous motor (PMSM) is investigated in this paper. The electromechanical coupling transmission system in the shearer is equivalent to a concentrated mass model for the purpose of establishing the system dynamic model by the Lagrange–Maxwell equation. Then, the Routh–Hurwitz criterion is used to determine the torsional vibration critical point and stability region for the Hopf bifurcation for the cutting transmission system. According to the Routh–Hurwitz stability criterion, the Hopf bifurcation type and the effect of the supercritical Hopf bifurcation in the torsional vibration of the cutting transmission system are analyzed. Furthermore, based on the washout filter, the Hopf bifurcation controller is designed for suppressing the transmission system’s large vibration amplitude and unstable oscillation. In addition, the influences of the linear gain and nonlinear gain on the bifurcation point and the limit cycle amplitude are discussed. Finally, the numerical simulation results indicate the effectiveness of the designed controller. The research achievements can provide a theoretical basis for design or optimize the cutting transmission system of high-reliability shearer driven by PMSM.
