Four control modes of servo drive

1.Feedback compensation open loop control. The accuracy of open-loop system is low, because the step error , start stop error and mechanical system error of servo driver will directly affect the positioning accuracy. This system has the advantages of both open-loop and closed-loop, that is, it has the stability of open-loop and the accuracy of closed-loop.

What is the principle of air conditioning and refrigeration

When the temperature is relatively high in the hot summer days, I believe many of them are also inseparable from the air conditioner. In the summer, it can be said that this life is given by the air conditioner. Everyone knows that the air conditioner can cool and heat, and can adjust the temperature according to your own settings to give yourself a comfortable feeling. However, few people know what is the principle of air conditioning and refrigeration? here we come to find out.
