The effect of stiffness constant, viscosity damper coefficient and variable mass on the damped frequency and the relative damping ratio of the system were studied.
研究了系统刚度、粘性阻尼系数尤其是变质量等参数对系统固有频率和阻尼比的影响。
2
The system with variablecoefficient is also discussed.
对于变系数的微分系统也作了相应的讨论。

We assume that the motion of controlled object is describedby linear ordinary differential equations with variablecoefficient, and the final states ofthe system form a convex region of phase space.
