Control modes refer to the different methods or strategies used to manage and regulate systems or processes. These modes can vary based on the context, such as in engineering, robotics, or computer systems. Common control modes include open-loop control, where the system operates without feedback, and closed-loop control, which uses feedback to adjust actions based on performance. In addition to these basic types, control modes can also include manual control, where a human operator makes decisions, and automatic control, where systems operate independently based on pre-set parameters. Understanding these modes is essential for optimizing performance and ensuring effective system management.
