Application of direct MRAC in PI controller for boost DC/DC converter

Lunde Ardhenta, Ramadhani Kurniawan Subroto


Almost all electronic components require a DC power supply at present days. The needs of DC power supplies from low voltage scales, medium voltages such as generators, to high voltage scales for high voltage electricity transmission. The improvement of PI controller performances is presented in this paper. The adaptation gains improve transient response of DC-DC Boost Converter several operating conditions. MIT rule is applied as an adaptive mechanism to determine the optimal control parameters in some conditions. A used adaptive control technique is Direct MRAC, this method as able to control system with some various input voltage. The proposed method has a stable response and able to reach the model reference smoothly. However, the response of the system has instantaneously overshoot and follow back the response of model reference. The rise time, settling time, overshoot, and steady-state for step response are some objectives that determine whether the adaptation gains work properly. The success of adaptive control is the determination of the adaptation gains.
