摘要
介绍了起落架支柱加载系统的工作原理,描述了电液伺服加载系统工作特点,对加载过程中产生的多余力进行了分析与分类。针对多种形态的多余力,提出了复合补偿控制方法,即速度补偿控制和端端补偿控制,并将补偿控制方法应用于加载控制系统控制律中,对采用复合补偿控制方法的前后进行了试验数据对比。试验结果表明,采用复合补偿控制方法能明显消减起落架收放过程中(特别是起动和到位时)产生的多余力,大幅提高了对气动力载荷的跟踪精度,取得了良好的工程应用效果,具有很好的推广应用价值。
The working principle of loading system for landing gear pillar is introduced,and working characteristics of electro-hydraulic servo-loading system are also described,and redundant force produced during loading process is analyzed and classified.A composite compensation control method which is namely speed compensation control and end-to-end compensation control is proposed according to various forms of redundant force.We compare the testing data before and after using the composite control algorithm.The experimental results show that we can significantly reduce redundant force during the process of loading by using the composite compensation control method(especially at the starting and the arriving moments),and also tracking precision of aerodynamic load is greatly improved,and a good engineering application effect is obtained,which has good popularization and application values.
