Servo Control is a closed-loop control methodology that uses feedback signals — typically from encoders or resolvers — to precisely regulate the position, velocity, or torque of an actuator. A servo controller computes the error between a desired setpoint and the measured output, then drives a servo motor or hydraulic actuator to minimise that error, making servo control foundational to high-precision robotic joint control, CNC machining, and collaborative robot safety systems.
