Implement of digital PID Controller Based on FPGA and the System Co-simulation
This paper presents the hardware implementation of PID control algorithm based on FPGA.The design adopts the three levels pipeline and ping pong operation in order to strike a balance between the speed and the exhausted FPGA resources.In the process of verifying the design performance,the paper introduces a sine microstepping driver system model of stepper motor.This model needs PID control to generate the ideal sine wave phase current,achieving the constant torque output.The system adopts co-simulation method.The simulation chooses EDA Simulator link MQ as an interface to connect the Modelsim and the Simulink.The co-simulation method breaks the gap between software and hardware design,and accelerates the function simulation.The simulation result demonstrates that the design can achieve conventional analog PID control.
