Delta Bağlantı Fırçasız Motor için Alan Odaklı Kontrol kullanan Sistemin FPGA Tasarımı ve Gerçeklemesi

Abstract

This paper presents FPGA(Field Programmable Gate Array) design and implementation method of system using FOC (Field Oriented Control) for delta connection BLDC (BrushLess Direct Current) motor. Brushless direct current motors are electro-mechanical units commonly used in daily life, industry, military and space applications. FOC method is used in applications that need constant torque of these motor types. FOC algorithm can use various PWM (Pulse With Modulation) methods while controlling BLDC motors. SPWM (Sinusoidal Pulse Width Modulation) is one of the most common methods for 3 phase inverter applications. FPGA’s that provide timewise certainty, high reliability, high speed performance and process simultaneous operation are intelligent units useful for motor applications. In this work, it was used Mojo V3 development board that had an FPGA from Xilinx Spartan-6 family. Mojo V3 development board can be used easily because programmer connecting with usb to computer is provided on board. FPGA was designed and implemented by using VHDL language through design flexibility and robustness. While implemention of FPGA, UART module, Telemetry/Telecommand module, FOC calculation module, PID controller module, Speed calculation module, SPI (Serial Peripheral Interface) communication module, SPWM module are designed by VHDL. As the result of this work has been compared delta connection brushless motor and star connection brushless motor difference when FPGA implements FOC method.
