Behavior of the Closed-Loop System
  • Load increases → output voltage tends to drop → PI increases duty cycle → inductor stores more energy → output voltage is restored.
  • Input voltage drops → similar action: PI compensates by increasing duty cycle.
  • Stable voltage regulation with small overshoot and fast settling, depending on tuning.
Benefits of PI Closed-Loop Boost Converter
  • Maintains output voltage under disturbances
  • Compensates for component aging and drift
  • Simple implementation (compared to full PID or adaptive control)
