Simulation and application of the electric power steering system simulation platform based on Simulink

The principle of the electric power steering system is introduced in this paper, and the simulation platform based on Simulink/Simscape is established. The mechanical structure of the steering gear, the timing scheduling strategy, the hardware control circuit, and the integration of the software control algorithm are modeled and verified in detail. It is proved that the simulation model is reliable and highly precise. The simulation platform is used to analyze the actual problems, and propose an improvement plan. The results show that the platform can improve the intelligence of development and quickly locate, effectively reproduce and analyze actual problems, and reduce the trial-produce cost of the early production line, which has a certain guiding significance for software and hardware development.
