Research on dynamic load emulation algorithm for electric vehicle driving motor test bench

In the process of developing an electric vehicle test bench, control accuracy is often low due to interference and other factors. To address this problem, this paper proposes a dynamic load emulation algorithm based on dynamic matrix control. Firstly, we create a detailed model of the distributed electric drive system. Then, we analyze the process of dynamic load emulation and propose an algorithm based on dynamic matrix control. Comparative simulations and bench tests are conducted to verify the algorithm. The results demonstrate that the proposed algorithm can achieve hardware-in-loop (HIL) test and improve test accuracy, as intended.
