<span lang="EN-US">In this paper, virtual synchronous converter (VSCon) is modelled which behaves as synchronous generator including its all real-time characteristics in operating inverter. This VSCon is used to synchronize grid and inverter while integrating distributed generated power to microgrids. The frequency and voltage synchronization can be controlled by using synchronous generator mathematical model is installed into the inverter. The whole unit of VSCon operated is simulated in Matlab/Simulink for observing all consequences for synchronizing voltage, frequency and phase-angle. It is verified that the next generation energy resources can be integrated into microgrid making synchronization grid-inverter using VSCon.

Modelling accurate response from hydraulic system in practice is difficult, especially establishing right mathematical model and getting all the parameters for certain hydraulic component. In this paper we mentioned two different different approaches for modelling hydraulic components, specifically Moog G761-series, made by company Moog. Approaches mentioned in this paper are using classical Matlab Simulink environment to show example of the first order model. Main focus is on using Matlab Simulink Simscape, which already includes some of the basic hydraulic components. We discussed problems and challenges when obtaining and simulating real components. We developed our own Simulink Simscape model for simulating Moog G761 servovalve. Simulation results were compared with the datasheet values from Catalog.

Aircraft Recovery

The aircraft recovery systems have been drawn more attention for its ability on offering cushioning landing in recent years. However, many previous researches mainly focus on the cylinder or rectangle air bags where the upper surface is orthogonal to the flank side. This kind of airbag will not meet the requisite stability and security because it might be bended by payload under the misalignment forces. In this light, a more stable frustum of cone parachute-airbag system is proposed and the cushioning mathematical model is established. Based on the theories of thermodynamics and mechanics, the expressions of velocity and deceleration are derived. The effects of initial parameters on airbag cushioning properties are analyzed and the simulation results are shown. The results can provide references for the future design of aircraft recovery system.
