An engineer adjusts the control circuit on a prototype board.

Definition

1. Noun:
   • A feedback circuit that subtracts from the input: A control circuit is an electronic circuit that uses feedback to compare the actual output of a system with a desired input or setpoint. It then generates a control signal that is subtracted from the input to reduce any error and regulate the system's performance.

Usage Examples

• Noun:
  • The thermostat uses a control circuit to maintain a constant room temperature.
  • Engineers designed a new control circuit to improve the robot's precision.
  • A malfunction in the control circuit caused the system to become unstable.

Advanced Usage

• In Control Theory: In technical contexts, a control circuit is a fundamental component of a closed-loop control system, often specifically referring to a negative feedback loop where the feedback signal is subtracted from the reference input.
  • The stability of the amplifier is ensured by its internal control circuit.

Variants and Related Words

• Feedback Loop: A broader term for the complete path of signal from output back to input.
• Closed-loop Control: A system that uses feedback to automatically adjust its operation.
• Error Amplifier: A specific component within a control circuit that amplifies the difference between the input and feedback signals.

Synonyms

• Regulator Circuit: A circuit designed to maintain a specific parameter.
• Negative Feedback Circuit: A circuit where the feedback signal opposes the input.

Related Phrases

• To implement a control circuit: To design and install such a circuit in a system.
  • They needed to implement a control circuit to manage the motor's speed.
