摘要
电动助力转向(EPS)系统是汽车的核心部件,采用功率硬件在环仿真测试技术可以缩短系统的开发时间、降低开发成本,同时降低开发风险,已经成为开发流程中非常重要的一环。以EPS用相移30°的双三相永磁同步电机(PMSM)为研究对象,提出了一种基于电力电子变换器的电机模拟器方案,以实现对不同负载条件下的电机动、静态电气行为模拟,为EPS系统的控制算法开发和故障模拟测试提供了高效平台。仿真结果验证了所提方案的有效性和可行性。
The electric power steering(EPS)system is the core component of the car.The use of power hardware-in-the-loop simulation test technology can shorten the system development time,reduce the development cost,and reduce the development risk,so it has become a very important part of the development process.A dual three-phase permanent magnet synchronous motor(PMSM)with a phase shift of 30°is used as the research object,and a motor emulator scheme based on a power electronic converter is proposed to simulate the dynamic and static electrical behaviors of the motor under different load conditions.It provides an efficient platform for the control algorithm development and fault simulation tests of EPS system.Simulation results verify the effectiveness and feasibility of the proposed scheme.
