np是numpy的缩写。
numpy是数字python的缩写。
系统识别的例子是用python编写的
numpy只是一个数组函数库。
系统识别非常重要。
我看着Amesim部分,想知道Amesim没有有效的模拟模型是多么有用。
我写我自己的模拟器。 这对我来说并不难。 困难的部分是确定阀门的型号。 如果没有有效的参数,模拟将不会有用。
系统识别对于确定模拟中每个组件使用的参数是必要的。
我认为制造商的液压组件不提供其组件的模型是可耻的。
即使液压软管具有液压电容,当软管位于阀门和活塞之间时,液压电容也会降低执行器的固有频率。
基本上,如果没有模拟组件的模型,Amesim就没有那么有用。 该模型由系统识别确定。
I used the computer translator. It takes too much time to fix the translation
np is the abbreviation of numpy.
numpy is short for numerical python.
The system identification example is written in python
numpy is just a library of array functions.
System identification is very important.
I look at the Amesim section and wonder how useful is Amesim without valid models for simulation.
I write my own simulators. That is not hard for me to do. The hard part is determining the model for the valve. Without valid parameters the simulation is not going to be useful.
System identification is necessary to determine the parameters for each component use in the simulation.
I think it is shameful that the manufacturers hydraulic components do not provide models for their components.
Even hydraulic hose has hydraulic capacitance that reduces the natural frequency of the actuator if the hose is between the valve and the piston.
Basically, Amesim is not that useful without a model for the components in the simulation. The model is determined by system identification.
