บทคัดย่อ
Normally power supplies provide a constant output voltage. A DC-DC converter in most of the applications is controlled by a voltage mode or a current mode controller. The DC converters are employed to feed electric vehicles, telephone sets and civil invertors, or for induction motors and frequency control. In this regard, optimal exploitation of DC transformed by classical controllers has been a controversial issue in reputable journal publications. Due to their switching property included in their structure, DC-DC converters have a non-linear behavior and their controlling design is accompanied with complexities. However, by employing the average method, it is possible to simplify the system as a linear system and exploiting linear control methods. In this article, an attempt is made to control the buck converter by PI and PID controllers. By using PID controller and genetic algorithm, a new adaptive control method model is introduced. A Genetic algorithm is applied to discover the supreme values for PID controller's parameters within a short time period. The improvement of the current control response is the result of the simulation. ฉ 2013 IEEE.
