Development of Sensorless Control Drive For Permanent Magnet Synchronous Motor Using a System-on-Programmable-Chip

Abstract
This paper presents a System-on-Programmable-Chip (SoPC) solution to develop a sensorless control drive for permanent magnet synchronous motor (PMSM). To evaluate the effectiveness of SoPC, the Hardware/Software co-design method using SoPC is firstly introduced and presented. Then it is applied to design a sensorless speed control IC for PMSM drive. In this SoPC, it has two modules to construct a fully digital drive controller. One module performs the function of the speed loop control, speed command and speed estimation based on extend Kalman filter (EKF). The other module performs the function of the current loop control for PMSM drives. The former is implemented by software using Nios embedded processor due to the need of complicated control algorithm and low sampling frequency control. The latter is implemented by hardware due to the need of high sampling frequency control but simple computation. The results demonstrates the performance efficiency of the proposed integrated solution. Keywords- FPGA, NIOS, System-on-Programmable-Chip, synchronous motor, Kalman filter.
