The development of this thesis entitled "Use of the algorithm of ant colony for the tuning of a PID controller applied to an RC circuit", aims to implement a program based on the multi object ant colony algorithm with restrictions as a method to tune a PID controller applied to a first-order RC circuit, and evaluate its performance by comparing it with conventional tuning methods such as the Ziegler and Nichols reaction curve method and Matlab's PID Tuner tool. For the execution of the experimental tests, a control system was implemented, which basically consists of an RC circuit, with a resistance of 10 KΩ and an electrolytic capacitor of 470 uF; a data acquisition card which consists of an Arduino Uno board and an MCP 4725 digital analog converter; and the Labview software which was programmed to be used as a PID controller. To perform the simulations of the RC circuit control system,...
