“…There are many factors that cause the electric vehicle powertrain systems to oscillate, and the most favored by researchers is the vehicle longitudinal acceleration oscillation caused by the instantaneous change of the motor output torque, which brings uncomfortable experience to the drivers and passengers (Akbar et al, 2019; Karamuk and Ozturk, 2019; Scamarcio et al, 2020b; Zhou and Guo, 2022). The transmission shaft is a flexible part, and the change in its damping ratio and elastic coefficient will cause the system to oscillation (Figel et al, 2019; Reichensdrfer et al, 2018; Zhu et al, 2015).…”

Aiming at the oscillation in the electric vehicle powertrain systems, a control strategy based on the structural singular value [Formula: see text] is proposed. To solve the problem of robustness under parameter uncertainty, the traditional [Formula: see text]-synthesis needs to obtain all-pass characteristics through the weight function in the nominal system, which reduces the perturbation suppression ability of the system. Unlike the previous use of [Formula: see text]-analysis as a system performance criterion, this paper starts from the essence of parameter uncertainty problems and designs controllers based on the relationship between parameter uncertainty and nominal systems, using structural singular value [Formula: see text] as a performance constraint. The result shows that the [Formula: see text]-analysis not only takes into account the robustness and disturbance rejection ability but also reduces the controller order. In addition, the oscillation suppression effect in the presence of transmission backlash is verified, and the [Formula: see text]-analysis can suppress the oscillation better than the [Formula: see text]-synthesis.

“…Since the shock of the powertrain can only be reduced but not eliminated, the dampers or active damping methods are also designed to reduce the influence of shock. [13][14][15][16] As the vehicle industry progresses, electric vehicle becomes an inevitable trend. However, it has also introduced new problems to the vehicle powertrain, such as the electro-mechanical coupling effect 17,18 that is caused by the addition of the driven motor.…”

The main purpose of this manuscript is to analyze the stability of the shock response of the electric vehicle (EV) powertrain when considering the electro-mechanical coupling effect. The nonlinear drive-shaft model of the powertrain is built using the Lagrange method, based on which the shock response equation is also deduced. Meanwhile, the number and properties of the equilibrium points are studied. Two kinds of equilibrium points, saddle node and central point, which can induce different dynamic behaviors are found. The simulation results show that the trajectory of the shock response may be unstable if the parameters are chosen in the region that has a saddle node. If the parameters of the powertrain fall into the region that has only one central point, the trajectory of the shock response will be attracted by the stable limit cycle. Therefore, to ensure that the shock response is more stable, the parameters should be chosen in the region where only one central point is present.
