Research on Satellite Power System Based on MPPT Technology by Wenshuang ZHANG, Wentao YU, Qiang WEI

“…According to the need of power system for GEO satellite,the plan design and simulation based on Maximum Power Point Tracking (MPPT) technology were designed and simulated.It could reduce the power loss in power transport line and made full use of the output power of solar array.Based on the research and simulation for solar array,the simulation of all the power system was fi nished.The result of simulation provides that it can complete the MPPT function and stabilize the bus voltage.Last,the new plan and the traditional one were compared,which shows the advantage of the new plan and lays a foundation for next power system.…”

Robust Control of Electric Vehicle Powertrain Torsional Vibration based on μ-method by Duan Xiaoya, Yu Peng, Zhang Tong, Sun Ling

“…In view of the torsional vibration of an electric vehicle（EV） driveline,based on the blendingμ integrated robust control theory,the control method of driveline is studied.Firstly,the driveline uncertainty model of a central-driven pure EV is established,considering the high-order unmodeled uncertainty of permanent magnet synchronous motor and the parameter perturbation.Then,μ-method is adopted to design the driveline robust controller.Finally,in order to verify the validity of the designed controller,the simulation and calculation are conducted by using Matlab / Simulink.Results show that the control strategy can enhance the robust performance and robust stability of the system,and reduce the possibility of system instability effectively.…”

Formal modeling and analyzing method for database security policy by Rong WANG, Min ZHANG, Deng-guo FENG, Hao LI

“…Because of the high-level abstraction,insufficient description of database states and constraints,it was difficult to find the tiny flaws in design and implementation.Based on PVS,a method for formal description and analysis of data-base security policy was proposed,which was more close to the actual database,more widely used in reality,and more complete in describing the safe properties,more extendible of the model,and ensure the efficiency of modeling and veri-fication.Finally,this method is applied in the security policy modeling and analyzing of BeyonDB,which is a commer-cial database,find some security risks in the system design,and thereby verify its effectiveness.…”
