Where is the electro-hydraulic servo system suitable for use?

Because of the above advantages, electro-hydraulic servo system is very suitable for occasions with large load and fast response speed. The "large load" here can be popularly understood as large load quality. It is nothing more than large aircraft, large hydraulic testing machines, large ships and other fields.

Application scenario of electro-hydraulic servo system

What is the difference between the electro-hydraulic servo valve control hydraulic cylinder system and the electro-hydraulic servo variable pump control hydraulic cylinder system?

The dynamic response of hydraulic cylinder controlled by electro-hydraulic servo valve can be faster, but this is realized at the expense of system efficiency. It is well understood that the efficiency of valve control system is lower than that of pump control.

What is electro-hydraulic servo valve?

The common electro-hydraulic servo valve is an electro-hydraulic continuous control valve. It is the core of the whole electro-hydraulic servo system. The performance of the whole system basically depends on the valve.

What are the existing problems of electro-hydraulic servo valve?

Mainly focus on:

1. Parameter uncertainty 2. Digital analog nonlinearity 3. Parts interchangeability 4. Quality consistency 5. Reliability

What are the design difficulties of the current electro-hydraulic servo valve control hydraulic cylinder system?

The system generally adopts feedback control, which needs to focus on the following aspects:

1. Stability 2. Accuracy 3. Rapidity

Although it has something to do with us, we can't have both stability, accuracy and speed. It's difficult to control the balance between the three, and it's difficult to achieve by relying on the preliminary design alone.
