Review Questions

• How does robust adaptive control enhance system performance in uncertain environments?
  • Robust adaptive control enhances system performance by allowing real-time adjustments to control parameters in response to uncertainties and variations. This adaptability ensures that even when faced with disturbances or changes, the system maintains stable operation. The integration of robust principles means that the system can effectively counteract the effects of uncertainty while still achieving the desired outcomes.
• Compare robust adaptive control with traditional control methods in terms of handling disturbances.
  • Robust adaptive control differs from traditional control methods by actively adapting to disturbances rather than relying solely on fixed parameters. Traditional methods may struggle when faced with unexpected changes, leading to reduced performance or instability. In contrast, robust adaptive control continuously monitors the system and modifies its parameters, ensuring it remains effective regardless of environmental shifts or internal changes.
