CES Transactions on Electrical Machines and Systems 2017年第3期1卷 265-272页

作者： Xinjie Yu Xukun Liu Department of Electrical Engineering Tsinghua UniversityBeijingChina State Key Laboratory of Power System BeijingChina

The pulsed power supply(PPS)is one important component in the electromagnetic launch *** inductive PPSs have attracted researchers’attentions with the major advantages of high energy storage density(over the capacitive PPSs)as well as simple structure and easy control(over the rotating mechanical PPSs).As for the inductive PPSs,the circuit topology of the basic module will directly determine the comprehensive performance of the whole *** the perspectives of working principles,strengths,weaknesses,and comprehensive performance,this paper presents a historical and technical review of the major circuit topologies for the inductive PPSs.

Modeling and Stability Analysis of DC-DC Buck Converter via Takagi-Sugeno Fuzzy Approach

Modeling and Stability Analysis of DC-DC Buck Converter via ...

2008 3rd International Conference on Intelligent System and Knowledge Engineering(ISKE 2008)

作者： Kamyar Mehran Damian Giaouris Bashar Zahawi School of Electrical Electronic and Computer Engineering Newcastle University Newcastle upon Tyne UK Member IEEE

The DC-DC voltage-mode controlled buck converter is a nonlinear, nonsmooth system that presents different circuit topologies within one switching cycle. This paper develops a Takagi-Sugeno fuzzy approach for modeling this circuit to cap- ture all the essential nonlinearities that occur in fast time scale. Based on the resulting model, we propose tractable mathematical stability analysis for identifying fast-scale instabilities of the converter, more specifically the edge of bifurcation phenomena, employing nonsmooth Lyapunov functions. The search for the Lyapunov functions are formulated as Linear Matrix Inequalities （LMI） feasibility problem which easily can be solved using up- to-date interior point methods.
