self-sustained oscillation

When the elasticity deformation of the mechanical system becomes larger, there is not much difference between the resonance frequency and the cutoff frequency, even gets into the band, it might cause the system self-excitation and oscillation.

当机械系统的弹性变形较大时，其谐振频率与截止频率很接近，甚至落入带宽中，引起系统的自激振荡。

Self-tuning PID control parameters results virtually have no overshoot and get stability in short time, and have less oscillation at the set target angle value.

从控制结果上参数自调整PID控制结果几乎没有超调，稳定时间短，在设定的目标角度值附近振荡少。
