Which of the following is a step in a control process?

The correct choice encompasses multiple crucial aspects of a control process. Data acquisition is the initial step where relevant information is gathered from various sources, such as sensors and instruments, to understand the current status of a system. This information is essential for making informed decisions in the control process.

Data feedback refers to the process of sending information back to the system after evaluation. This feedback is critical for comparing the current state with the desired state, allowing adjustments to be made to ensure optimal performance.

Including both data acquisition and data feedback as steps in the control process highlights the continuous cycle of monitoring and adjusting necessary for effective system control. Pre-design analysis, while important in planning and preparation stages, does not fall within the actual control process that consistently regulates system behavior during operation. Overall, these steps are integral to maintaining control over electric motor systems and ensuring smooth operation.
