To implement a PID controller in MATLAB:

Using MATLAB Code:

1. Define your system transfer function:

   s = tf('s'); G = 1 / (s + 2); % Example plant

2. Create the PID controller:

    

   Kp = 2; Ki = 1; Kd = 0.5; C = pid(Kp, Ki, Kd);

3. Connect controller and plant:

   T = feedback(C * G, 1); % Closed-loop system

4. Plot step response:

   step(T); title('Step Response with PID Controller');

---

Using Simulink:

1. Open Simulink → New Model

2. Add blocks: Step Input, PID Controller, Transfer Function, Scope

3. Set parameters in PID block (Kp, Ki, Kd)

4. Run the simulation and observe results in the Scope
