摘　　要：结合用伪随机信号进行系统在线辨识的原理,采用工控机作为控制计算装置,辅以PCL-818L数据采集卡,设计了完整的实验系统。并对一个具体的电液伺服系统进行了在线辨识,通过实验验证了辨识结果的正确性。The principle of process system on-line identification with pseudo random signal was introduced. Using IPC to take control counting assembly, aided by PCL-818L data acquisition card, the integrated experimental system was designed. The online identification to a concrete eletro-hydralic servo system was carried out, and the identification result was validated through the experiments.
