To compensate for this effect, a method is proposed in which velocity feedback signal is added to the original controller to reduce the limit cycleamplitude.
为补偿间隙的影响，本文提出了在不改变原有的控制器基础上，通过引入速度反馈而减小间隙极限环的方法。

The loads and the distribution of stress amplitude frequency are obtained by cycle count and reliable data for fatigue design are provided by probability density function fit.
用循环计数法求出载荷及应力幅频率分布，用概率密度函数拟合，为疲劳设计提供可靠性高的数据资。

Through changing some parameters such as type, frequency, amplitude, offset, and so on, it can get the amplitude eigenvalue that corresponding with the cycle signal and the stochastic signal.
