دمیدن فعال از لرزش پیچشی در نیروی گذار وسیله نقلیه قدرت تقسیم

In this paper, a Linear-Quadratic-Gaussian (LQG) controller with estimator has been implemented for the suppression of torsional vibration on the powertrain of a power-split vehicle caused by an abrupt acceleration. Two motor/generators in the transmission are applied to improve the drive comfort and guarantee the dynamic response. An equivalent model of planetary gear has been put forward to simplify the transmission. The simulation results show that the LQG controller suppresses the vibration effectively.
