More-electric aircraft is a new technical trend for modern aircraft, which does not need hydraulic braking system as traditional. A novel electro-hydrostatic actuator( EHA) based on pump and valve cooperating controlled for aircraft braking system is proposed. The principles and mathematic model are described. The simulation results for EHA and aircraft braking system show that the EHA and braking system have higher dynamic performance and it can meet the requirements of the more-electric aircraft braking system.%多电飞机已成为现代飞机的发展趋势,其刹车系统不再采用传统的液压刹车.提出一种用于多电飞机刹车系统的泵控和阀控相结合的电静液刹车系统.首先分析了电静液作动器的工作原理和数学模型,对电静液机构进行了单独的控制仿真；接着对飞机刹车系统进行数学建模,并将这种电静液作动飞机刹车系统进行控制仿真.仿真结果表明,基于电静液作动器的刹车系统具有良好的刹车性能,适用于多电飞机刹车系统.
