Long-term performance evaluation

Definition

Long-term performance evaluation is the systematic assessment of the effectiveness and efficiency of control systems over an extended period, typically focusing on their adaptability and ability to maintain desired performance levels in varying conditions. This evaluation plays a crucial role in identifying how well a system can adjust to changes, manage uncertainties, and sustain optimal operation, which is vital for real-world applications of control strategies.
