relative margin of error的意思|示意

The problem of satisfactory PID control for a class of stochastic systems with constraints on dynamic error coefficient, steady-state output variance and relative stability margin is considered.

研究一类随机系统具有期望的动态误差系数、稳态输出方差和相对稳定裕度约束的满意PID控制问题。

The developmental threshold was fixed at 26 of disease index based on the relative error margin analysis.

根据感病损失量方程，病情很轻时损失甚微，经相对误差限法分析，将病情指数26定为该病的发生指标。
