电梯应用中基于超级电容器的能量回收系统改进控制策略

This paper proposes an improved control strategy for a supercapacitor (SC)-based energy recovery system (ERS) for elevator applications. The ERS is connected to the dc-link of the elevator motor drive through a bidirectional dc-dc converter for storing and then recovering the braking energy. A system of two fuzzy-logic controllers is introduced for online adjusting the dc-link voltage through the ...
