N2 - In the DC distributed power system of the more electric aircraft (MEA), it is necessary to have a LC filter in the input of boost converter due to electromagnetic interference (EMI) and sharp input impulse voltage. Whereas, the interaction between boost converter and poorly damping filter may cause instability throughout the system., The problem may be solved by adding resistor or increasing capacitance, but it also increases the power consumption, volume and weight. However, the volume and weight are important performance indexes in the MEA. In this paper, we will introduce a virtual capacitor to solve the above problem without extra volume and weight. Firstly, the closed-loop control parameters of boost converter are designed by SISOTOOL of MATLAB. Then, the model, which is used to analyze the stability of cascade system with LC filter, is derived based on the Takagi-Sugeno (TS) fuzzy theory, and then a public Lyapunov function is found by (linear matrix inequation) LMI tool of MATLAB to estimate the stability of the system. Finally, the simulation results confirm the validity of the proposed stability analysis and control method.
