Development of Vibration Reduction Strategy Using Active-Damping Control of IPM Motor and HSG of Eco-friendly Vehicles

摘要

This paper proposes a vibration control strategy for hybrid electric vehicle caused by resonance vibration of engine and traction motor. Based on measured speed ripple and design parameters of engine and motor, we obtain speed resonance estimation model consisting of inertia and stiffness of engine, motor, shafts and tire of vehicle. Then, we suggest the vibration suppression scheme using speed resonance estimation model with IPM traction motor and High-voltage Starter Generator. With proposed control scheme the actual speed ripple and vibration is reduced to less than 10% of conventional one. Furthermore, we can achieve high driving performance without additional hardware modification.
