摘要

当前，由于电源的多样化，变流器的使用越来越受到人们的关注。特别是，DC-DC变换器用于确保负责为直流微电网提供恒压的直流电源的稳定性。因此，使用经典和现代控制方法来确保连接到恒定功率负载(CPL)时馈电系统的稳定性。本文以平方误差积分(ISE)、时间加权平方积分(ISET)和控制平方积分(ISSC)为性能指标，比较了丢芬丁方程、根轨迹、线性二次调节器和李雅普诺夫方程的极点配置控制方法。

Comparative study of control strategies for oscillation damping in DC microgrids

: Nowadays, the use of converters is attracting increasing attention due to diver-siﬁcation of electric power sources. In particular, DC-DC converters are used to ensure the stability in the DC supply responsible for feeding a DC microgrid with constant voltage. Thus, classical and modern controls methodologies are used to ensure the stability of the feed system when connected to a constant power load (CPL). This paper compares control methodologies for pole allocation using Diophantine equation, root locus, linear-quadratic regulator and the Lyapunov equation by using performance indices as integral of square error (ISE), integral of square weighted by time (ISET) and integral of square of control (ISSC).
