Abstract: The variable frequency speed regulation system of EPS (electric power steering) surface PMSM (permanent magnetic synchronous motor) is made up of the PMSM、 the inverter、 the rotor position sensor and the control unit. The control of surface PMSM electric power steering system includes the torque control and the vector control. The torque control is the control target of the surface PMSM electric power steering system. And the vector control is the control of stator current vector of the surface PMSM. The control process of the surface PMSM electric power steering system is illustrated. The setting of the assist characteristic, the coordinate transformations and the PWM technologies of the control system of the surface PMSM electric power steering are analyzed.

Transactions of the Chinese Society for Agriculture Machinery (CSAM), in charged of China Association for Science and Technology (CAST), sponsored by CSAM and Chinese Academy of Agricultural Mechanization Science(CAAMS), started publication in 1957. It is the earliest interdisciplinary journal in Chinese which combines agricultural and engineering. It always closely grasps the development direction of agriculture engineering disciplines and the published papers represent the highest academic level of agriculture engineering in China. Currently, nearly 8,000 papers have been already published. There are around 3,000 papers contributed to the journal each year, but only around 600 of them will be accepted. Transactions of CSAM focuses on a wide range of agricultural machinery, irrigation, electronics, robotics, agro-products engineering, biological energy, agricultural structures and environment and more. Subjects in Transactions of the CSAM have been embodied by many internationally well-known index systems, such as: EI Compendex, CA, CSA, etc.
