Future more electric aircraft (MEA) can be seen as a direct current microgrid (dc MG). While dc MG can generally achieve safe, efficient, and reliable operation of the system, constant power loads (CPLs), unknown resistive loads, dc source voltage variations, and disturbance inputs might degrade the overall stability and performance if they are not compensated in the control design procedure. In this article, a fast-reaching condition-based sliding mode control (SMC) is proposed for the dc MG. The fast-reaching law contains two terms that improve the transient performance by forcing the system states to reach a sliding surface with two different rates. This attribute enhances the speed of convergence of the states to the sliding surface compared to conventional SMC. Additionally, the suggested method is resilient to system parameter uncertainties, which is indispensable in practice. The proposed controller is implemented to a dc MG that is supplied by an uncertain dc source and feeds CPLs and resistive load with time-varying power and resistance. OPAL RT results illustrate the robustness and fast convergence of the planned SMC controller.
