Abstract
In future all-electrical ships with Medium Voltage DC distribution, the power system stability can be jeopardized by the presence of constant power loads, due to the negative impedance characteristic of their tightly regulated converters. In order to solve this problem we apply backstepping as a nonlinear control technique to the converter interfacing the generation side and which supplies the bus. In this work we demonstrate two versions of backstepping, which are compared to a centralized linearizing state feedback controller taken from literature.
