摘要
针对直升机旋翼助力器被动加载中高频率载荷模拟,设计了基于DCS的上、下位机结构的计算机控制系统;上、下位机分别运行在不同的操作系统,采用不同的软件开发环境,使用RS485进行上下位机之间的通信,实现了高频加载下的实时控制;同时,在分析该系统被动加载中多余力产生机理的基础上,基于互相关频响辨识,设计了一种针对单频正弦或者多频率正弦的叠加的多余力补偿方案;该方案结构简单,易于调整,试验结果表明,文章设计的动态加载控制达到很好的控制效果。
Based on Distributed Control System, designed a helicopter booster passive load system, in which, master and slave computers ran on different OS, different software development environments were used, and RS485 was used for the communication. Besides, analyzed the principle of plus torque in load system, processed a new type of cross-correlation method for identification of system frequency response, based on which designed a compensation for Plus Torque. The project is simple and easy to adjust. Test results showed that the system accurately simulated the aerodynamic load of booster.
