摘要
在并联混合动力汽车以电机起动的过程中,驱动电机(永磁同步电机)处于突然加载的工况,当电机参数在一定范围内时,电机会产生混沌现象。并联混合动力汽车的驱动电机出现混沌现象,不但对自身的寿命以及输出特性产生不利影响,而且在电机与车辆传动系统结合后,也会把这种极其不稳定的输出传递到整车驱动系统中,最终会引起更加复杂、不稳定运动的产生。应用ADVISOR2002软件,在ECE-EUDC循环工况下,探讨了永磁同步电机的温度变化对电机定子电阻RS、绕组电感L、转子永磁体磁链ψr的影响。针对电机以上3个参数对整个电机混沌系统的影响,基于状态反馈和模糊控制理论设计了模糊反馈混沌控制器。仿真结果表明:整车冲击度J由最大值0.02降到0.001(m/s3)。最后通过硬件在环(HIL)试验,验证了所设计控制器的有效性。
During the start-up process of a parallel hybrid electric vehicle, if the drive motor （PMSM） is in sudden load conditions, and the motor parameters are within a certain range, then the motor will produce chaos phenomenon. Chaos phenomenon not only causes an adverse effect on the life of the motor itself, but also resulting in the occurrence of the unstable situation of the vehicle and great harm happened to its own drive parts caused by more extremely unstable and volatile output to the transmission system after being in combination with the transmission of the vehicle. In ADVI- SOR2002 software, with the effect of temperature changes on the rotor permanent magnet, the article discussed trends of the motor stator resistance Rs, winding inductance L and permanent magnet flux ψr under the ECE-EUDC cycle conditions. In terms of the impact of the three parameters discussed a- bove and based on the state feedback and fuzzy control theory, a chaos controller was to be designed in this paper, and after that we used vehicle jerk J as the indicator, and the simulation results were also be given. Simulation results show that the vehicle J dropped from a maximum of 0.02 to 0. 001 （ m/s3 ）. Finally, we used hardware in the loop （HIL） test to verify the effectiveness of the controller designed by this paper.
