摘要
针对双电机混动系统开发中控制策略实时验证需求,提出一种基于dSPACE SCALEXIO平台的永磁同步电机(PMSM)高精度硬件在环(HIL)仿真建模方法。通过建立包含逆变器电压解算、d-q轴电磁方程、机械运动方程的完整数学模型,实现电机动态特性精准模拟;利用FPGA板卡部署实时仿真模型,突破微秒级计算时效瓶颈。模型成功通过开环及闭环验证,表明建模方法有效。该建模方法可为电机控制器信号级HIL测试提供有效解决方案,显著降低实车测试风险并加速控制算法迭代。
To address real-time verification needs for control strategies in dual-motor hybrid system development,This paper proposes a high-precision hardware-in-the-loop(HIL)simulation modeling method for permanent magnet synchronous motors(PMSM)based on dSPACE SCALEXIO platform.By establishing a complete mathematical model incorporating inverter voltage calculation,d-q axis electromagnetic equations,and mechanical motion equations,accurate simulation of motor dynamic characteristics is achieved.Using FPGA boards to deploy real-time simulation model breaks through microsecond-level computational time bottleneck.The model successfully passes open-loop and closed-loop verification,demonstrating effectiveness of proposed modeling method.This method provides an effective solution for signal-level HIL testing of motor controllers,significantly reducing real vehicle testing risks and accelerating control algorithm iteration.
