Abstract

This paper proposes proportional-integral/proportional gain controller parameter tuning in a two-degrees-of-freedom (2DOF) control system using the fictitious reference iterative tuning (FRIT) method for permanent magnet synchronous motor (PMSM) speed control using a field-programmable gate array (FPGA) for a high-frequency SiC MOSFET (metal oxide semiconductor field-effect transistor) inverter. The PI-P (proportional-integral/proportional) controller parameters can be tuned using the FRIT method from one-shot experimental data without using a mathematical model of the plant. Particle swarm optimization is used for FRIT optimization. An inverter that uses a SiC MOSFET is presented to achieve high-frequency operation at up to100 kHz using a switching pulse-width modulation (PWM) technique. As a result, a high-responsivity and high-stability PMSM (permanent magnet synchronous motor) control system is achieved, where the speed response follows the ideal response characteristic for both the step response and the disturbance response. High-responsivity and optimal disturbance rejection can be achieved using the 2DOF control system. FPGA-based digital hardware control is used to maximize the switching frequency of the SiC MOSFET inverter. Finally, an experimental system is set up, and experimental results are presented to prove the viability of the proposed method.

Summary

Introduction

This paper presents the use of the fictitious reference iterative tuning (FRIT) method for tuning of a two-degree-of-freedom (2DOF) proportional-integral/proportional (PI-P) controller in a new speed control system for a permanent magnet synchronous motor (PMSM) using a field-programmable gate array (FPGA) for a high-frequency SiC MOSFET (metal oxide semiconductor field-effect transistor) inverter. High-switching frequency operation can be achieved using the SiC MOSFET because of its superior material characteristics [1,2,3,4]. Variable-frequency drives (VFDs) can be operated efficiently at carrier frequencies in the 50 to 200 kHz range when using this device [5]. FPGA-based digital hardware control is used to ensure fast processing operation for the high-frequency switching of the SiC MOSFET inverter. FPGA has advantages, such as high-speed processing and rewritablility. High-speed calculation is obtained using the ability of hardware processing. The synthesis process, the generate programming file process and the configure target device process must be performed before downloading the programming file to an FPGA, so that
