This study tackles the issue of improving the design of the automatic voltage regulator system (AVR) based on the resulting transient response and steady-state error observed through the use of MATLAB. Focusing on the application of the AVR on the synchronous generator, three simplified designs were constructed and simulated as follows: an AVR without the controller, an AVR with a proportional-integral-derivative (PID) controller, and an AVR with a PID controller and an additional voltage sensor. Upon evaluating the systems on parameters such as the response and rise time, the percent overshoot, settling time, the steady-state error, the peak time, and the step response, the results strongly indicate that the automatic voltage regulator with a PID controller and additional voltage sensor had the best stability and the most ideal steady-state error with a proportional gain of 1. The integral and derivative having gains of 0 shows that it has no role in shaping the response of the chosen system. The system created here can be used in the biomedical field like EVG Signal Transmission monitoring. © 2020, World Academy of Research in Science and Engineering. All rights reserved.
