  The electro-hydraulic servo system has outstanding advantages such as fast response speed, large output power, and high control accuracy. Therefore, it is widely used in aerospace, military, metallurgy, transportation, engineering machinery and other fields. The electro-hydraulic position servo control system uses liquid as the power transmission and control medium, and uses electrical signals to stop the control input and reaction.

  Just input a certain regular input signal, the actuator can start, quickly and accurately reproduce the changing law of the input quantity. The accuracy of the fundamental request of the performance of the servo system is high. The accuracy of the servo system refers to the accurate level at which the output can reproduce the input. Good stability. Stability refers to the system under the action of a given input or external interference.

  After a short conditioning process, it can reach a new or restore to the original equilibrium state. Quick response. Response speed is an important indicator of the dynamic quality of the servo system, which reflects the tracking accuracy of the system. The speed range is wide. The range of speed regulation refers to the ratio of the relatively high speed and the relatively low speed that the consumer machinery requests the motor to provide.

  Low speed and high torque. In servo control systems, constant torque control is usually requested at low speeds, and the motor can provide greater output torque; constant power control at high speeds, with sufficient output power. Can frequently start, brake and switch between forward and reverse. Varieties of servo systems Servo systems can be divided into three types: electric, hydraulic and pneumatic according to the different servo drives; they can be divided into metering servos and power servo systems according to different functions.
