Hydraulic Servo Drive Systems are control systems that utilize hydraulic power to achieve high-precision, high-response-speed servo control. They are widely applied in industrial fields requiring high power, high load stiffness, and rapid dynamic response. The core principle involves precise tracking of input signals (such as position, speed, or force) by hydraulic actuators (e.g., hydraulic cylinders or motors) under closed-loop control, enabling efficient and stable motion control.
I. Working Principle
Signal Input and Comparison The system receives external input signals (e.g., position commands) and compares them with feedback signals (actual position, speed, or force) to generate an error signal.
Controller Processing A controller (e.g., PID controller) calculates the control quantity based on the error signal and outputs an electrical signal to the servo valve.
Servo Valve Regulation The servo valve converts the electrical signal into a hydraulic signal, adjusting the flow rate and pressure of hydraulic oil to drive the hydraulic actuator.
Actuator Movement The hydraulic actuator (e.g., hydraulic cylinder) generates displacement or force to drive the load.
Feedback Detection Sensors (e.g., displacement sensors, pressure sensors) continuously monitor the actuator’s output and send feedback signals back to the controller, forming a closed-loop control system.
II. System Composition
Hydraulic Power Source: Hydraulic pump station providing high-pressure hydraulic oil.
Servo Valve: High-precision electro-hydraulic servo valve for electrical-to-hydraulic signal conversion.
Actuator: Hydraulic cylinder or motor driving the load.
Sensors: Displacement, speed, and force sensors for feedback signals.
Controller: PLC, DSP, or dedicated motion controller implementing control algorithms.
Auxiliary Components: Oil tank, filters, coolers, pipelines, etc.
III. Technical Features
High Power Density Capable of delivering high power, suitable for heavy-load and high-inertia applications.
High Response Speed Servo valve response time can reach milliseconds, ideal for dynamic control.
High Load Stiffness Exhibits high stiffness and strong resistance to disturbances.
Precise Control Closed-loop control achieves micron-level position accuracy and low-speed stability.
Wide Adjustable Range Enables speed and force control over a broad range by regulating hydraulic oil flow and pressure.
Metallurgy: Rolling mill pressure systems, continuous casting mold vibrators.
Testing Equipment: Material testing machines, vibration tables, fatigue testers.
