What is the purpose of a PID controller?

Step 1: Understand that a PID controller is a tool used in control systems to manage how a system behaves.
Step 2: Learn that PID stands for Proportional, Integral, and Derivative, which are three different ways the controller makes adjustments.
Step 3: Know that the Proportional part adjusts the output based on the current error (the difference between the desired value and the actual value).
Step 4: Understand that the Integral part looks at past errors and helps eliminate any remaining steady-state error over time.
Step 5: Realize that the Derivative part predicts future errors based on the rate of change, helping to smooth out the response.
Step 6: Combine all three parts to see how the PID controller works together to keep the system stable and accurate.
