Definition

1. Adjective:

   • Of or involving servomechanisms: Relating to or constituting a type of automatic control system that uses feedback to precisely govern the position, speed, or other output of a mechanism.

2. Noun:

   • A control system that converts a small mechanical motion into one requiring much greater power; may include a negative feedback system: A device, often a motor (a servomotor), that is part of a servomechanism. It automatically corrects the performance of a machine using error-sensing feedback.

Usage Examples

• Adjective:

  • The robotic arm uses a servo mechanism for precise movement.
  • He installed a servo amplifier to improve the control loop.

• Noun:

  • The model airplane's wing flaps are controlled by a small servo.
  • A feedback signal from the sensor adjusts the servo.

Advanced Usage

• "servo-controlled": Describes a system or component whose operation is automatically regulated by a servomechanism.

  • The servo-controlled valve maintains constant pressure.

• "servo loop": Refers to the complete closed-loop control circuit, including the servo, sensor, and controller.

  • Stability is critical in the design of the servo loop.

Variants and Related Words

• Servomechanism (n): The complete automatic control system that includes a servo.
• Servomotor (n): The specific motor that provides the power in a servo system.
• Servosystem (n): Another term for a servomechanism.

Synonyms

• Actuator (n): A device that causes a machine to operate, but not necessarily with feedback control.
• Feedback controller (n): A general term for a control system using feedback.

Related Phrases

• Servo drive: A combination of components that powers and controls a servomotor.
• Servo feedback: The signal returned to the controller to report the servo's actual status.
