飞机配电系统容错技术的设计研究

Fault-tolerant design of aircraft power distribution system

为了提升电力飞机配电系统电压供应品质,本论文利用重构控制理论来设计电压调节器用以有效的达到电压调节的目的。利用Dobson和Chiang提出的电力系统模型并假设在配电系统中电容器与变压器为有效的控制输入,在本论文提出了电压调节器设计准则。更进一步我们以容错控制的观念来设计主动式及被动式容错控制律,使得飞机配电系统在控制器发生故障或异常情况时,依然可以达到电压调节的目的。

Issues concerning the design of an effective voltage regulator in a power system are studied in this paper. By adopting a model from Dobson and Chiang （1988） and assuming the available control input being the capacitor and tap changer, two classes of Variable Structure Control （VSC） voltage regulators are proposed to promote the quality of power supply. These regulators are shown to be able to achieve the regulation task. The reliability issues of the regulation when one of the control inputs experiences outage are also taken into account through VSC technique in this paper.
