This basic method uses solenoid valves to direct compressed air into either side of the actuator, causing extension or retraction. It operates in binary states with no intermediate positioning.

• Simple to implement but offers limited precision
• Suitable for applications like valve opening/closing where only end positions matter
• Requires minimal components
• Works well for high-speed, repetitive tasks

Utilizes proportional valves that modulate air flow based on electrical input signals. This allows incremental positioning across the actuator's full stroke, enabling precise control of intermediate positions.

• Integrates feedback sensors for closed-loop adjustment
• Compensates for air compressibility and load variations
• Ideal for applications needing variable positioning

Combines proportional valves with advanced feedback systems and a controller. The controller continuously compares actual position/pressure with setpoints, adjusting air flow dynamically to minimize errors.

• Offers higher precision than basic proportional control
• Reduces hysteresis and improves repeatability
• Capable of ±0.1mm accuracy

Adjusts air pressure on either side of the actuator to control force output, indirectly regulating position for load-sensitive tasks.

• Uses pressure regulators and sensors to maintain desired force levels
• Prevents overloading of delicate components
• Often paired with position sensors for dual control of force and position
