针对现代航空机轮加载试验台高可靠性和高精度的要求,提出了基于可编程计算机控制器(PCC)的新型机轮加载试验台控制系统的实现方法；系统以贝加莱PCC为控制核心,通过传感器实时采集载荷信号,采用模糊自整定PID控制算法实现对试验台液压系统的控制,完成机轮加载试验；同时,通过高速以太网与工业控制计算机进行通信,实时上传并且记录试验数据；试验结果表明,该系统具有稳定性高、实时性好、控制精度高等特点.%In view of the requirement of high reliability and high precision in aero-tyre load test bed, a new type of control system based on PCC is designed. B&R PCC is exploited as the control core, through the real -time sampling of pressure signal by sensor and the fuzzy self-tuning PID, the load test is achieved. Meanwhile, the PCC communicates with the industrial control computer by high -speed Ethernet to upload and record test data in real time. The experimental results show that the system has a high stability, high real -time property and high precision.
