Abstract :
The Electric power steering (EPS) is a typical multidisciplinary system. Its development cycle is long, and the development process is complicated. The uncertain change of the road and car driving conditions makes the EPS system strong in the nonlinearity and uncertainty, and the development more difficult. To meet the rapid verification and performance testing for the EPS system, this paper designs the controller using the robust H algorithm of the mixed sensitivity, tests and analyzes comprehensively the EPS system using the loop simulation based on dSPACE. The results show that the H∞ algorithm of the mixed sensitivity makes the EPS system have good robustness, the loop simulation technology can effectively shorten and simplify the development process.
