Study on multidisciplinary system of electric power steering based on dSPACE

摘要

Electric power steering (EPS) is a typical multidisciplinary system, its development period is long and process is complexity. The non-linear characteristics and uncertainties caused by different driving cycles and roads make development more difficult. To verify the EPS system, the H∞ robust controller was designed and the hardware-in-loop(HIL) simulation platform of EPS system based on dSPACE was set up. The result shows that the H∞ algorithm has good stability and robustness, HIL technology makes application development so much easier and faster.
