三端口直流换流装置及其无源控制仿真研究
Simulation of Three-port DC Converter and Its Passivity-based Control
摘要
Abstract
The three-port converter studied in this paper includes three ports,i.e.,power supply,energy storage and load,in which the load can directly obtain electric energy from the power supply or the energy storage port.First,a mathematical model of Euler-Lagrange form is established,a passivity-based controller is designed,and the simulation of passivity-based control(PBC)is carried out.The PBC strategy has advantages of strong global stability and strong ro-bustness to system parameter deviation and external disturbance in the nonlinear system.Based on the PBC theory,the passivity of the three-port converter system is demonstrated.Through the PBC and single-phase-shift control of dual-ac-tive-bridge(DAB),the energy transfer between the three ports is realized.Finally,simulation results in Matlab/Simulink are given,which proves that the load in the device can directly obtain electric energy from the energy storage port and run safely,stably and reliably.关键词
