Microprocessor Based PID Controller Design and Implementation.(Dept.E)

Abstract

This paper presents the design and implementation of PID controller based on the use Of microprocessors. The implemented technique tokes into account the problems associated with hardware as well as software, o.g. interfacing resolution. Bignol leveling microprocessor limitation …etc . The technique combines the advantages of the conventional PID controller (e.g. simplicity, case of design, and suitability for different typers of processes and those of microprocessors and microcomputer (e.g. low cost easy tuning and adjustment and enhanced controller reliability). The designed controller is applied to control the position and speed of DC motor under different load and reference input conditions. Satisfactory results regarding process performance are obtained. Thsrsfors, the use of microprocessors and microcomputer is recommended for control of physical processes.
