Abstract
DC converters are an important part of DC systems such as hybrid (PV and wind turbine) system. Buck DC/DC converter one of this converter is the main control in DC voltage regulator. The desired performance of this DC converter is following the reference voltage and having a fast response. This paper designs controllers based on the principle of backstepping control to operate a DC converter. Modification to adaptive backstepping is promised to improve the response generated by conventional backstepping. The using of a DC motor as a load make the control system has the aim to stabilize the DC bus voltage and DC motor speed. The effectiveness of the proposed control is verified by simulation. The PID controller is utilized for comparing with the proposed controller. The performance produced by the proposed controller has a simple design and good response.
