PID Controller for 1st & 2nd Order System in MATLAB Simulink.

Simulate first and second-order systems with a PID controller in MATLAB Simulink. Explore improved control performance with integral, derivative actions.

This MATLAB Simulink project demonstrates the simulation of first-order and second-order systems under the control of a Proportional-Integral-Derivative (PID) Controller. The model enables users to see how the additional derivative term helps reduce overshoot and improves system stability, while the integral action improves steady-state error.

Advantages of PID Controller:

1. Fast and Accurate Response = Combines P, I, and D actions to provide a quick response with minimal error.
2. Eliminates Steady-State Error = The integral term ensures that the output eventually reaches and stays at the setpoint.
3. Predicts and Dampens Oscillations = The derivative term anticipates future errors and reduces overshoot and oscillations.
4. Improves Stability and Transient Performance = Offers better control during changes in system input or disturbances.
5. Versatile and Tunable = Suitable for a wide range of dynamic systems, and parameters can be finely tuned for specific performance.
6. Better Control Over System Behavior = Provides a balance between speed, stability, and accuracy.
7. Widely Used in Industrial Automation = Standard in motor control, robotics, temperature systems, and many other control applications.
8. Easy to Implement with Simulink = MATLAB Simulink offers ready-made PID controller blocks with auto-tuning features.
