Title: Brushless DC motor control system based on FPGA research
Abstract: This article describes an FPGA-based implementation of brushless DC motor speed regulation system,proposed system can implement the motor speed and high precision output,and can always change the motor rotation direction.The system application of FPGA to generate PWM circuit,solves the traditional motor drive circuit peripheral design complex and anti-interference ability bad such defects.PWM signal via Avalon bus for DC motor control,motor rotational speed signal through the Hall-effect sensor feedback to fuzzy PID controllers,and fuzzy PID controller in a given signal value to compare the revised output.Fuzzy PID controller generated by FPGA meanwhile implementing system simulation.Simulation results show that:PWM module and fuzzy PID controller based on FPGA generates simple structure,control,flexibility,and strong anti-interference ability,and meet the actual requirements of the motor speed.
