Intelligent Microcontroller Using Runtime Coefficient Update Techniques for Disturbance Robust Output Control

Abstract

Direct current (DC) motors are commonly seen around us and are used for the operation of controlled objects in various fields. In general, the operating characteristics of these DC motors determined through proportional-integral-differential (PID) control in the microcontroller. However, in a previously designed PID controller, once the PID coefficients are determined, it is difficult to change their values. In this paper, a PID coefficient update technique was applied to a disturbance occurring in a DC motor at runtime to increase the response speed of the system and reduce the root mean square error. This technique can be applied to various industrial applications that require precise control even when there is a disturbance in the runtime.
