servoactuated
Servoactuated refers to any mechanism whose motion is controlled by a servo, a device that combines a motor with a feedback sensor in a closed-loop arrangement to achieve precise control of position, velocity, or torque. In a servoactuated system, a controller issues a command signal to a servo amplifier, the amplifier drives the motor, and feedback from a sensor is used to minimize the error between the actual state and the commanded state.
Typical components include a servo motor (often brushless DC or AC servo), an encoder or resolver for
Common control modes are position servoactuation, velocity servoactuation, and torque servoactuation. In position mode the goal
Applications span robotics, CNC machinery, precision positioning stages, aerospace actuators, and automated valves or dampers. In
Advantages include precise tracking, high bandwidth, and compatibility with modern control architectures. Drawbacks include higher cost
