Questions & Step-by-Step Solutions
In a PID controller, what does the 'I' term represent?
Step 1: Understand what a PID controller is. It is a type of control system used to manage the behavior of machines or processes.
Step 2: Know that PID stands for Proportional, Integral, and Derivative. Each term has a specific role.
Step 3: Focus on the 'I' term, which stands for Integral.
Step 4: The Integral term accumulates the error over time. This means it adds up all the past errors.
Step 5: The purpose of the Integral term is to eliminate steady-state error, which is the difference between the desired setpoint and the actual output that remains after the system has settled.
Step 6: By using the Integral term, the controller can adjust its output to correct any persistent error.
