The Research for Test Measure of Machine Time of DC Servo System

提出用曲线拟合函数测量直流伺服系统机械时间常数的方法,推导了阶跃法和频率法测量系统机械时间常数的数学模型。此方法比传统的数学解析法和实验法测试准确,并解决了转角范围受限的系统机械时间常数测试的难题。

The test method of least square estimation for the machine time constant of DC servo system is presented.The mathematic models of leap and frequency testing methods for the machine time constant are also introduced.The method of least square estimation tests more precisely than traditional mathematic and experimental methods,and solves the problem for testing machine time constant of angle limited systems.
