Design and application of permanent magnet motor controller with FPGA

Abstract

The permanent magnet synchronous motors (PMSM) are the sinusoidal motors with the supply current and the induced voltage waveform. In general, AC and DC can be fed from one source. They react quickly to the applied voltage. Due to the limitations in the mechanical design of PMSM, the flux in the air gap is not regular. This irregularity causes momentum fluctuation in the motor. This fluctuation problem can be solved by using various controllers in the controller structure. In the literature, PMSMs are controlled by different control methods such as direct torque control (DTC), field-oriented control (FOC). Various feedback systems have been used to eliminate the problem of torque fluctuation and PI controller is the most widely used. In this study, PMSM structures and control methods were examined. The advantages and disadvantages of the FPGA based PMSM controller structures have been examined in recent years. In addition, an FPGA controller has been designed to control the PMSM with the vector control method. In order to avoid moment fluctuations during the control, a PI controller, and the current data received from each phase as feedback used in the controller.
