PI Controller for 1st & 2nd Order System in MATLAB Simulink.
This MATLAB Simulink project illustrates the simulation of first-order and second-order systems under the control of a Proportional-Integral (PI) Controller. The model enables users to visualize how adding an integral term improves the system’s steady-state error and overall performance compared to basic P control.
Advantages of PI Controller:
  1. Eliminates Steady-State Error = The integral action ensures that the output reaches the desired setpoint without a constant offset.
  2. Improved Accuracy = More precise control than a simple P controller, especially for systems requiring zero steady-state error.
  3. Better Disturbance Rejection = Can correct for external disturbances more effectively due to the memory (integral) term.
  4. Stable and Smooth Response = Balances fast response and stability without introducing excessive overshoot when tuned properly.
  5. Simple Design and Implementation = Easier to design and implement compared to full PID controllers, while still offering enhanced performance.
  6. Enhanced Low-Frequency Gain = Makes the system more responsive to low-frequency changes, beneficial in many real-world applications.
  7. Widely Used in Industry = Suitable for many applications like motor speed control, temperature regulation, and process control.
