FRIT based PI tuning for speed control of PMSM using FPGA for high frequency SiC MOSFET inverter

Abstract

This paper proposes PI gain controller parameters tuning by using Fictitious Reference Iterative Tuning (FRIT) method for speed control of PMSM using FPGA for high frequency SiC MOSFET Inverter. PI controller parameters can be tuned by using FRIT without mathematical model of plant from one-shot experimental data. Particle Swarm Optimization (PSO) is utilized for the optimization of FRIT. The inverter using SiC MOSFET is presented to achieve high - frequency operation up to 100 kHz with a switching PWM technique. As the result, high response and good stability control system of PMSM can be achieved so that speed response follows the ideal response for step response and disturbance response. Digital hardware control based on FPGA is used to maximize the switching frequency of SiC MOSFET inverter. Finally, an experimental system is set up and some experimental results are demonstrated.
