Abstract
PID controllers have been widely used in industrial fields. Since the PID parameters have a great influence on the stability and performance of the control system, many approaches have been proposed to determine them. In this article, we propose double helix structured DNA algorithms to design the type of PID controller and optimize the PID parameters. The double helix structured DNA algorithms employ a DNA encoding method based on a base-64 notational system to represent the PID parameters, define various mutation methods, and have a recovery function to preserve a DNA strand that has good fitness value. A computer simulation shows that we can get satisfactory results with the proposed method.
