What components make up an Open-Loop Control System?

An Open-Loop Control System is characterized by the absence of feedback. This means that the system operates based solely on pre-set conditions without any adjustments made in response to the output. In this context, the combination of a Servo Amplifier and a Servo Motor is a prime example of how an open-loop control system functions.

In an open-loop system, the controller (in this case, the Servo Amplifier) sends a command to the actuator (the Servo Motor) to perform a specific action, such as moving to a designated position. However, there is no feedback mechanism in place to assess whether the motor has reached that position or to correct any errors. This highlights the straightforward operation of the open-loop system where input goes through the controller to the actuator without any verification or correction based on the output.

The other choices represent components that are typically part of different control system architectures. For example, a feedback loop is essential in a closed-loop system, sensors and actuators work together in a variety of configurations but are not exclusive to open-loop systems, and a power supply and motor combo can be part of various system types but does not specifically illustrate the operational principles of an open-loop control system. Therefore, the selection of the Servo Amplifier and Servo Motor
