| Abstract: | Based on the model for brush-less DC motor(BLDCM) and the dynamic model for electric power steering(EPS) system,the simulation models for BLDCM control and EPS performance are set up.The EPS controller hardware with ARM7LPC2131 as its core and MC33034P120 as drive module is designed,and the requirements of power assistance,aligning and damping controls on controller hardware are analyzed.The flow charts of main program and its subroutine for A/D and speed signals acquisition and interrupt service are given.... |
