“…Therefore, many scholars used the method of series correction or feedback control to reduce the vibration near the resonance frequency, which could produce a damping effect to reduce torsional vibration or body shake. 13–16 Berriri et al 13 used the engine speed as the feedback input, and improved the damping effect of the resonance point of the transmission system by introducing band-pass filter series correction. Zhong and Wei 14 used pole controller to effectively reduce the vibration transmissibility near resonance frequency during engine start-up and stop.…”

Torsional vibration occurs when the hybrid vehicle transmission system is influenced by the multiple excitations and the dynamic loads caused by mode switching. Torsional vibrations of transmission system directly affect the stability, reliability, and safety of vehicles. In order to suppress the torsional vibration, this paper studied the active vibration control algorithm for the hybrid powertrains under rapid acceleration. Primarily, the architecture and the dynamic modeling of the drive system of the hybrid vehicle was built. Moreover, the hybrid control system including engine controller, motor controller and transmission controller was proposed. Furthermore, an adaptive active control controller was constructed to solve the torsional vibration problem. And model prediction control (MPC) and Butterworth filter control were combined into the controller. Finally, the efficacy of this active method for vibration reduction under start-up conditions was simulated. The simulation results showed that the torsional vibration of the transmission system was reduced by 96%–99% with external interference and the system stabilization time was advanced by 93% without external interference. The adaptive control algorithm suggested in this paper effectively suppressed the torsional vibration of hybrid electric vehicles (HEV) when accelerating in pure electric mode, without affecting vehicles’ dynamic performance.

Due to environmental pollution concerns, emission regulations on internal combustion engines (ICEs) have been tightening and the importance of fuel efficiency has become pronounced. Thereupon, downsizing, downspeeding, turbo supercharging, and cylinder deactivation techniques have been implemented in designing modern ICEs. Despite their considerable benefits, these methods result in boosted torsional oscillations necessitating new vibration isolation technologies due to the limited performance of passive torsional vibration dampers. In addition, trade-offs are indispensable in the passive damper system designs since different engine operating points demand different values of oscillation attenuation parameters. Thus, this study was initiated to develop a novel active torsional vibration damper (ATVD) to attenuate the torsional vibrations of all engine operating points without making any trade-off and to open up a new comfort zone for the development of modern ICEs. Proposed ATVD is essentially a parametrically excited system that adjusts the stiffness rate, damping rate, and moment of inertia in accordance with a fuzzy logic control (FLC) law to maximize engine-borne torsional vibration attenuation capability. The ATVD performance is evaluated in a co-simulation environment by using a driving cycle with six engine operating points and its advantages over conventional passive dampers are demonstrated.

“…Fredriksson et al 4 designed PID, pole placement (PP), and linear-quadratic-Gaussian controllers for active cancellation of the torsional vibrations. The PP controller was applied to solve driveline vibration problems of HEVs during engine starts and stops [5][6][7] and oscillations in the driveline caused by elasticity and gear play. 8 A wellperforming motor can also help attenuate system vibration.…”

One of the key challenges with the development of hybrid electric vehicles is the noise, vibration, and harsh behavior, specifically the uncomfortable ride experience during launch. This paper focuses on the driveline vibration caused by the quick response of the traction motor in the launch condition of hybrid electric vehicles. A torsional vibration differential equation for frequency analysis, including a Ravigneaux planetary gear set, a reducer, a differential, half shafts, and wheels, is thus built. Based on the equation, many components of the power-split system are simplified to make the controller design easy. Finally, wave superposition control strategy has been proposed to suppress the vibration, in which the concept is delaying part of the input to superimpose with the original input to eliminate the output wave. In order to optimize the control effect, parameters of the controller are chosen according to the system response. The simulation outcomes demonstrate that wave superposition control strategy is effective in attenuating the vibration generated by hybrid electric vehicles during launch conditions.
