FPGA-Based PID Controller Implementation

Abstract

Proportional-Integral-Derivative (PID) controllers are widely used in automation
systems. They are usually implemented either in hardware using analog
components or in software using computer-based systems. They may also be implemented
using Application Specific Integrated Circuits (ASICs). This paper outlines
several modules necessary for building PID controllers on Field Programmable Gate
Arrays (FPGAs) which improve speed, accuracy, power, compactness, and cost effectiveness.
Two PID controllers for speed and position utilizing these modules are
implemented and used as experimental platforms to illustrate and test the designed
modules.
