A Servo-Controlled System is a feedback-based mechanism designed for precise control of a mechanical system's position, velocity, and acceleration. ⚙️ It works by continuously monitoring the output (e.g., motor position) with a sensor and comparing it to the desired input. Any difference between the two creates an 'error signal' which is then used to drive a motor or actuator to make corrective adjustments. This closed-loop system ensures that the output remains stable and accurate, making it essential for applications requiring high precision like robotics, CNC machines, and stabilizers.
