摘要
以地震模拟振动台(以下简称振动台)线性模型为基础,应用一阶灵敏度模型分析了振动台三状态反馈控制参数的灵敏度函数及其对系统动态特性的影响,用仿真的方法分析了三状态反馈参数的变化对系统输出特性的影响程度.
Based on the linear model of seismic simulating apparatus, one order sensitivity model is applied to analyze the sensitivity functions of 3-state feedback parameters of a seismic simulating apparatus and its effect on the dynamic characteristics of the apparatus. The degree of the effect of variation of 3-state feedback parameters on the apparatus characteristics is studied with digital simulation.
