Which components do open-loop and closed-loop systems share in common?

Open-loop and closed-loop systems both incorporate essential components that facilitate their operational processes, which includes the servo motor and the servo amplifier.

In both types of systems, the servo motor serves as the actuator that converts electrical energy into mechanical motion, allowing for the execution of tasks based on input signals. The servo amplifier is crucial as it amplifies the input signal in order to control the servo motor's performance, providing the necessary power to achieve the desired movement.

In a closed-loop system, feedback is used to regulate the control process, but the fundamental components involved in driving the motor and managing its power amplification remain the same as in an open-loop system. This shared characteristic highlights the core functionality of both types of systems, despite their different methodologies in managing input and response.

Thus, understanding the roles of the servo motor and servo amplifier underscores their significance in both open-loop and closed-loop control systems.
