Abstract
Electric power steering is a new power steering technology for vehicles.
Merit such as energy conservation , environmental protection that the person
has accepts the respectively big automobiles of world company and the
enterprise favour , home and abroad developing trend is to use electric
power-assistance to change to the hydraulic pressure power-assistance
vergence substituting tradition step by step.
The mathematic model the main body of a book is established
systematically with dyadic EPS of the tradition vergence post
power-assistance for the object of study,has given an automobile out electric
systematic power-assistance dynamics equation , has combined classics
control theory and the optimization algorithm, the parameter carries out
validity in applying to reality having studied , testifying this system on
systematic power-assistance.
This paper presents an elect ricpower steering system controlled by
P87C591 microp rocessor. The motor given torque is computed by
expertcontrol system. The practical output torque is closed-loop controlled.
