MPC5602P-Based Hardware Circuit Design for Electric Power Steering System

This paper analyzes the design requirements of high-performance EPS controller, on the basis of which, we select Freescale Power Architecture ECU MPC5602P special for EPS. By the means of Modular Design, we propose a new design for EPS controller hardware, which focuses on MPC5602P minimum system, power supply module, three-phase induction motor inverter module and sensor signal conditioning module. Meanwhile, we completed EPS controller program design process in the light of the induction motor vector control theory. Finally, our controller realized the control functions of the electric power steering motor after it was debugged.
