6 FAQs about [Servo hydraulic system energy storage cylinder]
What is electro-hydraulic servo pump control cylinder technology?
In this paper, electro-hydraulic servo pump control cylinder technology is proposed to replace the original valve-controlled cylinder technology with inherent system defects, and it is applied in an AGC hydraulic system .
What is servo hydraulics?
Aircraft control; Position control; Servovalve; Servo steering Servo hydraulics is a special application of hydraulic (hydrostatic) systems with the ability to amplify input signals and perform fast and precise position control of actuators, also sometimes speed or force control.
What are servo-hydraulic components?
The combination of electronic intelligence and hydraulic power is typical for modern control systems. Components for servo-hydraulic applications are similar to normal hydraulic components, but they require a higher degree of precision and speed, and are more expensive than ordinary components. They are presented here in short.
What is system flow in electrohydraulic servo system?
In an electro-hydraulic servo system, the system flow is used as an intermediate variable to control the output displacement/force/speed of the actuator, and it plays the role of a medium for energy transmission and conversion. Therefore, the control of the system flow is the essence of state control for the system actuator.
What is a servo valve?
Servo valves are key components for electro-hydraulic servo systems. Valves for servo hydraulics are directional valves that not only allow open and closed, but also intermediate positions. Input signals can be mechanical, hydraulic, pneumatic, but are in most cases electrical.
How to verify the control performance of a hydraulic servo system?
To verify the control performance of the proposed desired compensation output feedback controller (DCOFC), PI control (PI) and sliding mode control (SMC) with full state feedback are applied to the hydraulic servo system. In the system plant, the state variables are added with certain noise to simulate the measurement noise.
