“…Interaction has been observed in a range of systems, for example sub-synchronous resonance in land based power generation [7,8] causing early fatigue of mechanical components [9], challenges for wind power generation [10,11] causing gearbox failure [12], unpredicted faults in industrial processes such as mills [13], excessive vibration in electric and hybrid-electric vehicle drivetrains [2,14] increasing wear [4], and wave induced instability in marine propulsion systems [15]. Methods for mitigating electro-mechanical interaction include minimising gearbox backlash [16], control scheme disturbance rejection [17] and repositioning of resonant modes through design [18].…”

Abstract-The supply of electrical power is usually achieved by a generator, driven from a prime mover, by some form of mechanical drivetrain. Such an electro-mechanical system will have natural resonant modes in both the electrical and mechanical subsystems. The electrical generator provides a coupling between the subsystems, transferring not only useful power but also disturbances between electrical and mechanical domains: these disturbances may excite resonances resulting in cross-domain (electro-mechanical) interaction. This can lead to lifetime reduction in the mechanical components and instability in the electrical network, resulting in poor reliability for the wider system, and potentially catastrophic component failure. Electro-mechanical interaction is particularly critical in power generation systems onboard aircraft, because the generator is driven by a gas turbine via an inherently low-stiffness drive train. It is then critical to identify electro-mechanical interaction at the design stage so that these issues can be avoided. However, predicting the occurrence of interaction, through simulation, is challenging, requiring multi-domain models, operating with different time scales. This paper analyses an aircraft auxiliary power offtake to produce a reduced-order mechanical drivetrain model, allowing the modal frequencies to be predicted and crossdomain interactions to be modelled. A purpose-built electromechanical test platform is used to validate the model and demonstrate how electrical disturbances are passed through the generator to the mechanical system and affect the electrical network. Future research will use the test bed to demonstrate strategies for avoiding or suppressing unwanted interactions.

“…But the fact that the HEV is subjected to frequent stopping and starting of the engine to conserve fuel, or even too much stopping or starting of the electric motor, deserves some consideration in terms of vibrations or stressing of the engine, motor, or mechanical members associated with the system. Ito et al [10] have studied the vibration problem in an HEV engine in reasonable detail. In this particular system, a power split device, that is, the planetary gear system, is used to connect the various items shown.…”

“…However, relying solely on the TMH system was not able to express the vibrate situation of the driveline. Ito et al [11] explained that adding elastomers to the system could simulate the operation of the overall driveline accurately, and present the phenomenon caused by torque transfer. In addition to the half-shaft, this research added elastomer modules such as an internal combustion engine damper and tires to indicate the source of the low-frequency vibration on the driveline, and half shaft speed was fed back to control strategy for vibration reduction of the driveline system.…”

“…He et al [16] developed a three-stage control strategy to smooth the transition from electric mode to hybrid mode. Ito et al [11] proposed a control strategy that within the signal planetary gear hybrid system, while the internal combustion engine was having a large torque output to cause vibration, the signal was sent to control logic to calculate torque feedback by the gear ratio relationship. The torque feedback would be sent back to the controller changing the motor torque output signal to an equal but reverse torque to cause vibration neutralization.…”

In order to achieve better performance of fuel consumption in hybrid vehicles, the internal combustion engine is controlled to operate under a better efficient zone and often turned off and on during driving. However, while starting or shifting the driving mode, the instantaneous large torque from the engine or electric motor may occur, which can easily lead to a high vibration of the elastomer on the driveline. This results in decreased comfort. A two-mode power-split hybrid system model with elastomers was established with MATLAB/Simulink. Vibration reduction control strategies, Pause Cancelation strategy (PC), and PID control were developed in this research. When the system detected a large instantaneous torque output on the internal combustion engine or driveline, the electric motor provided corresponding torque to adjust the torque transmitted to the shaft mitigating the vibration. To the research results, in the two-mode power-split hybrid system, PC was able to mitigate the vibration of the engine damper by about 60%. However, the mitigation effect of PID and PC-PID was better than PC, and the vibration was able to converge faster when the instantaneous large torque input was made. In the frequency response, the effect of the PID blocking vibration source came from the elastomer was about 75%, while PC-PID additionally reduced 8% by combining the characteristics of the two control methods.
