本文对液压比例控制系统动态特性的微型机测试及如何将传统的阶跃分析,频率法分析和相关分析实验在微型机上实现“智能”化进行了深入的研究。实验结果表明:这种“智能”型的测试系统较常规仪器测试具有一系列优点。 In this paper, the dynamic characteristics of the hydraulic proportional control system of microcomputer testing and how to traditional step analysis, frequency analysis and correlation analysis experiments in the microcomputer to achieve “smart” into in-depth study. The experimental results show that this “smart” type test system has a series of advantages over the conventional test.
