Abstract: (1832 Views)
Nowadays, due to the widespread use of DC energy sources, DC microgrids (DCMG) have been attracted more interest. DCMG in the presence of constant power loads (CPLs) is prone to challenges such as instability. This paper introduces a nonlinear control strategy for a DC-DC buck converter feeding a CPL in a DCMG. This strategy includes adaptive controller using backstepping controller and sliding mode controller along with Extended Nonlinear Disturbance Observer (ENDO). This adaptive controller is able to overcome CPL problems; furthermore, the ENDO improves the robustness and dynamic of the system by estimating system disturbances more accurately than the conventional NDO. In order to verify the performance of the proposed controller, simulation in MATLAB/Simulink software and also experimental test have been done.
Keywords: Backstepping Sliding Mode Controller, Buck converter, Constant power load, DC Microgrid, Extended nonlinear disturbance observer.
