摘要： 考虑电驱动系统机械、电气与控制参数之间复杂的耦合关系，同时针对多变的运行工况和多方位的性能需求，提出了一种电驱动系统“机-电-控”参数协同优化设计方法。首先，基于永磁同步电机的降阶模型，建立了电机功率损耗计算模型，并结合齿轮传动系统功率损耗模型构建了电驱动系统功率损耗计算模型，进而，考虑汽车的实际行驶工况，建立了电驱动系统行驶工况综合损耗评估方法。随后，采用集中参数法建立了电驱动系统的动力学模型，以获取电驱动系统的动力学特性，并综合电机定子齿所受的径向力，实现对电驱动系统动态性能的全面评估。最后，以电驱动系统的总质量、循环行驶工况下的总能量损耗、转矩波动以及电机径向电磁力脉动作为综合优化目标，实现了机械、电气和控制三类参数的动态同步寻优。本文所提优化方法，其优化过程优化套优化，实现了机械、电气、控制参数的协同优化，为高性能电驱动系统提供了设计理论与方法。

Abstract: Considering the complex coupling relationship between mechanical, electrical, and control parameters of electric drive system, and aiming at its variable operating conditions and multi-directional performance requirements, a collaborative optimization design method of "machine-electric-control" parameters of electric drive system is proposed. Firstly, based on the reduction model of permanent magnet synchronous motor, the motor power loss calculation model is also established, and the power loss calculation model of the total electric drive system is constructed combined the power loss model of motor and gear transmission. Moreover, considering the actual driving conditions of vehicles, the comprehensive loss evaluation method of electric drive system under driving cycle is established. Then, the dynamic model of the electric drive system is established by the lumped parameter method to obtain the dynamic response of the electric drive system, and the radial force on the stator teeth of the motor is considered comprehensively to realize the comprehensive evaluation of the dynamic performance of the electric drive system. Finally, taking the total mass of the electric drive system, total energy loss under cyclic driving conditions, torque fluctuation and radial electromagnetic force fluctuation as comprehensive optimization objectives, the dynamic synchronous optimization of mechanical-electrical-control parameters is realized. The optimization method proposed in this paper, in which, the internal nested optimization is included, realizes the cooperative optimization of mechanical, electrical and control parameters, provides the design theory and method for high performance electric drive system.
