Step 1: Understand that PID stands for Proportional, Integral, and Derivative.
Step 2: Focus on the 'I' in PID.
Step 3: The 'I' stands for Integral.
Step 4: The Integral part accumulates the error over time.
Step 5: This accumulation helps to eliminate steady-state error, which is the difference between the desired setpoint and the actual output that remains after the system has settled.
