<abstract abstract-type="short" xml:lang="en"><p><![CDATA[Abstract: This work presents the analysis of the behavior, performance and robustness of the closed loop control system of an Automatic Voltage Regulator (AVR) through a dependent type PID controller (ANSI/ISA), where the proportional, integral and derivative gains are tuned using two methods, the metaheuristic optimization method called the Sine-Cosine Algorithm and the Ziegler- Nichols last-gain method. The models of the AVR and the controller are presented, simulations are carried out using the MatLab-Simulink® software. Finally, simulation results between the two methods presented are provided.]]></p></abstract>
