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: Electric power steering Control Dynamics Fuzzy-neuro-net
