| Popis: | In this paper, a new technique is discussed to control a DC–DC power converter with non-minimum phase structure. DC–DC converters have physically nonlinear structure and need a nonlinear controller for better performance. Positive output elementary super lift Luo converter (POESLLc) is a new DC–DC converter with low losses, high efficiency, and high voltage gain. A backstepping controller is suggested for POESLLc. It regulates the output voltage based on pulse width modulation. The closed-loop control system is not necessarily robust against working point variations. Considering uncertainty in load, an adaptive scheme is adopted to achieve an excellent performance. Global stability of backstepping controllers is demonstrated by using Lyapunov theory. Some main features of the proposed controller are: robustness against uncertainty, fixed switching frequency, fast response, and elimination of the chattering compared with sliding mode control. Simulation results are demonstrated to verify the performance of the proposed controllers in different operating points. |
