摘要: 针对飞机高压、大功率所带来的节流损失急剧增加的问题,提出了一种根据飞机工作任务设定工作模式和输入给定量的智能泵源系统. 其控制与管理实际上是一个递阶计算机控制系统,上位机(机载公共设备管理计算机)负责根据飞行任务选择泵的工作模式和输入量设定(必要时还可以包括控制律的选择和控制参数的设定),下位机负责现场控制律的实现、控制量输出和数据采集等工作. 研制了智能泵的微控制器和原理样机. 所构成的智能泵源系统可以根据飞行任务需要选择工作模式并自动设定相应的输入量(压力、流量或负载敏感压差),实现对功率利用情况的有效管理,从而有效抑制系统的温升并提高飞机的机动性和生存能力.

Abstract: Aiming at the problems of the increase in orifice loss caused by high pressure and large power of the airborne hydraulic power system, a kind of intelligent power supply system which sets operation mode and reference input according to the assignment of the airplane was proposed. The control and management of the intelligent pump is really a hierarchical computer control system. The upper computer is responsible for the determination of operation mode and reference input. The lower computer, i.e., micro-controller, is responsible for the realization of the control law, the transformation of digit to analogue, and data acquisition. For the convenience of integration, a scheme of micro-controller was presented, it integrated the lower computer, signal condition circuit and servo amplifier, and the micro-controller was developed. The smart hydraulic power supply can select the operating mode and the input of controller according to the flight assignment, and realize the effective management of the power utilization, so that the rising of temperature is effectively restrained and the maneuverability and the existence ability are increased.
