Title: Implementation of FPGA on SPM Drive Using PI Controller
Authors: N. Krishna Kumari and G. Tulasi Ram Das and M.P.Soni
Abstract: This paper presents the FPGA implementation of a Direct Torque Control (DTC) for Surface Mounted Permanent Magnet Synchronous Motor (SPM) using PI controller. Reference stator flux is obtained with Maximum Torque per Ampere Principle (MTPA), which gives minimum stator ohmic losses resulting in maximum efficiency. The Direct Torque Control algorithm with PI controller is designed and implemented using VHDL. The complete digital controller algorithm is divided into two modules. From the first module position of flux vector is found based on the flux error, torque error and the sector. In this module the reference torque is obtained using PI controller from which the online reference stator flux is obtained. From the second module the switching state of the inverter is obtained based on the position of the flux vector. The digital controller algorithm is implemented on a Xilinx Spartan-3 FPGA board. The inverter keeps the same state till the outputs of the hysteresis controllers change states. So that when inverter is fed to the SPM it maintains a desired constant speed under different load conditions. Experimental and simulation results for transient response of the drive are tested and compared
