DESIGN AND IMPLEMENTATION OF DIGITAL PID CONTROLLER USING FPGA

Abstract: This paper presents the design and implementation of a digital Proportional-Integral-Derivative (PID) controller using Field Programmable Gate Array (FPGA) for precise speed control of a DC motor. The proposed PID controller enhances motor speed stability by continuously generating the control signal in real time using the difference between the reference speed and the measured motor output. The digital PID controller demonstrates efficient motor speed regulation, reduces the steady-state error, and fast response time. This FPGA-based implementation offers flexibility, scalability, and high-speed operation, making it suitable for various industrial automation and embedded control applications.
