Abstract

Moving toward more electric aircraft (MEA) concept, electrification of modern aircraft will consist of a large amount of constant power load (CPL), which giving tough stability problems and research opportunities. In such an application, on-board dc power system may have a time-varying system structure and operation pattern due to the flexibility of the distributed loads. This feature poses challenges for system stability and increases the difficulty of the stability analysis. To solve this problem, an interconnection and damping assignment (IDA) passivity-based controller (PBC) is proposed in this paper. Particularly, an adaptive interconnection matrix is designed for building the internal links in port-controlled Hamiltonian (PCH) system, and the virtual damping assignment technique is addressed to tune the dynamic characteristic. To meet all the electricity supply needs, the design procedures were introduced for determining the control law in both boost converter and buck converter cases. Simulation and experimental results are performed to confirm the proposed control algorithm. Results show that the proposed control approach ensures the stability and the fast response of the system in different cases when the CPL changes.
