Review Questions
How do closed-loop control algorithms differ from open-loop systems in their operation?
Closed-loop control algorithms differ from open-loop systems primarily by their use of feedback. While open-loop systems operate without monitoring the output and adjusting based on it, closed-loop systems continuously measure their outputs using sensors. This real-time feedback allows closed-loop systems to make automatic adjustments to minimize any error between the actual output and the desired setpoint, leading to improved stability and accuracy.
Discuss the role of sensors in closed-loop control algorithms and their impact on system performance.
Sensors play a critical role in closed-loop control algorithms as they provide the necessary data for monitoring the system's output. By continuously feeding this information back into the algorithm, sensors enable real-time comparisons between the actual performance and the desired setpoint. This feedback loop allows for quick adjustments to be made, significantly enhancing system performance by ensuring that deviations are corrected promptly, which is especially important in applications requiring precision.
