Robust Control of Electric Vehicle Powertrain Torsional Vibration based on μ-method by Duan Xiaoya, Yu Peng, Zhang Tong, Sun Ling

“…In view of the torsional vibration of an electric vehicle（EV） driveline,based on the blendingμ integrated robust control theory,the control method of driveline is studied.Firstly,the driveline uncertainty model of a central-driven pure EV is established,considering the high-order unmodeled uncertainty of permanent magnet synchronous motor and the parameter perturbation.Then,μ-method is adopted to design the driveline robust controller.Finally,in order to verify the validity of the designed controller,the simulation and calculation are conducted by using Matlab / Simulink.Results show that the control strategy can enhance the robust performance and robust stability of the system,and reduce the possibility of system instability effectively.…”

Mechatronic Joint Modeling and Simulation for Intermittent Chain Transmission System based on RecurDyn by Guo Bin, Tang Jun, Huang Wuxin, Liu Xiliang

“…In order to determine the motor drive motion of intermittent chain transmission,the recursive modeling approach based on relative coordinates in Recur Dyn is studied.Combining with permanent magnet synchronous motor model,the dynamics model of intermittent chain transmission system and motor model are established in Recur Dyn and Matlab / Simulink separately,and the correctness of the two models are verified.Using Recur Dyn / control module to combine with both,mechatronic simulation is carried out under three kinematic law of intermittent motion.The simulation results show that,compared to modification constant velocity（ MCV） kinematic law,modification sine（ MS） and modification trapezoid（ MT） kinematic law for intermittent drive is better,and MT kinematic law can give motor higher torque store margin and lower overload requirements.…”
