Abstract: After the definitions of steering system dynamics and inverse dynamics are given, the fuzzy-neuro-net based PD-controller is designed. With the multi-body dynamics model of steering system and the vehicle steering model established, the dynamics simulation of vehicle steering is carried out. Related experiment is performed on the taste table we designed. Both the simulation and experimental results show that the dynamics model is correct and control strategy put forward can improve the portability and sensitiveness of vehicle steering system.

Key words: Control, Dynamics, Electric power steering, Fuzzy-neuro-net
