基于IPMSM弱磁控制的电动汽车智能驾驶研究
Research on intelligent driving of electric vehicles based on IPMSM flux-weakening control
摘要
Abstract
To address the problem of collaborative matching between the powertrain and driving decision in intelligent driving of electric vehicles,as well as to improve vehicle response speed and control accuracy,an intelligent driving strategy based on IPMSM flux-weakening control was proposed,in which the intelligent driving decision module was implemented using a model predictive control algorithm.Based on the IPMSM mathematical model,an MTPA-FWC model was designed,and by optimizing the quadrature-and direct-axis currents,the motor response speed was enhanced and the speed regulation range was broadened.A model predictive control(MPC)controller based on vehicle single-track dynamics was designed,and polynomial trajectory planning was adopted in the Frenet coordinate system for overtaking maneuvers.The MTPA-FWC model was used to replace the original vehicle powertrain,and a CarSim-Simulink co-simulation platform was built.Through simulation verification under typical scenarios such as automatic cruising and automatic overtaking,it was shown that the powertrain integrated with MTPA-FWC could precisely cooperate with the MPC controller,satisfy the dynamic power demands of intelligent driving,and consequently improve both the dynamic performance and driving safety of the electric vehicle.关键词
