The difference between feedback and feedforward control is that feedback control aims to ________ errors.

Feedback control is a system used to manage and regulate the output of a process by comparing it to a desired setpoint. Its primary function is to detect any deviations or errors between the actual output and the desired output. When an error is identified, feedback control mechanisms work to eliminate this error by adjusting the input to the system. This iterative process enhances the accuracy and stability of the system by continually working to bring the output back in line with the target.

Eliminating errors is crucial in feedback control because it ensures that the system operates efficiently and within the desired parameters over time. For example, in temperature control systems, if the actual temperature deviates from the setpoint, the feedback control will trigger actions to correct the temperature, thereby minimizing or completely eliminating any discrepancy.

In contrast, feedforward control anticipates potential disturbances and adjusts the inputs proactively to mitigate future errors, rather than addressing them after they occur. Understanding this distinction highlights why the goal of feedback control is centered on eliminating errors.
