一个好的模型是非常困难的。
有许多参数来确定。
PID增益。
增益,阻尼因子,和固有频率的导阀。
增益,阻尼因子和自然频率的主阀。
阀芯摆率和泄漏的飞行员和主阀。
我会用一个集总模型,并使用从Bode图的数据来估计与仅有增益,阻尼因子和固有频率的简单模型。
A good model is very difficult.
There are many parameters to determine.
The PID gains.
The gain, damping factor, and natural frequency for the pilot valve.
The gain, damping factor and natural frequency for the primary valve.
The spool slew rates and leakage for the pilot and primary valve.
I would use a lumped model and use the data from the Bode plot to estimate a simple model with just a gain, damping factor and natural frequency.
