An Objective Function in control theory is crucial for assessing the performance of a system over time, making the choice of maximizing a measure of performance the correct answer. This function quantitatively expresses the goals of the system, allowing for evaluation and optimization of its behavior based on measurable criteria.

In practical terms, by maximizing this performance measure, systems can be adjusted to achieve optimal performance, whether that involves minimizing the error in a control loop, ensuring stability, or enhancing efficiency. This aligns closely with the principles of control theory where the focus is on achieving specific desired outcomes through the manipulation of system inputs and dynamics.

The other options do not accurately reflect the primary focus of an Objective Function. The number of inputs into a system does not directly relate to performance measurement, nor does the desired effect of human behavior align with an Objective Function’s purpose within a control context. Likewise, maximizing complexity contradicts the goals of many control systems, which typically strive for simplicity and effective operation rather than increased complexity. Maximizing a measure of performance consistently represents the primary aim in optimizing control system functionality.
