Abstract: To control the stable output of the direct current to direct current more effectively, the study is based on the improved adaptive sliding mode control method to explore the efficiency output of the boost converter. The results revealed that the adaptive sliding mode controller saved 26.21% of time compared to the conventional inductor control. The rotor position error of the adaptive inductor with improved phase-locked loop reduced by 28.16% compared to the conventional inductor control at a given speed of 300 r/min and 200 r/min, respectively. Moreover, the rotor position error of the adaptive inductor with improved phase-locked loop was further reduced compared with that of the traditional phase-locked loop. The performance stability of the improved adaptive sliding mode controller is well illustrated.
