What is the primary purpose of a derivative controller in a PID controller?

Step 1: Understand what a PID controller is. It is a control system that uses three components: Proportional, Integral, and Derivative.
Step 2: Focus on the Derivative part of the PID controller. This part looks at how fast the error is changing.
Step 3: Realize that the derivative controller predicts future errors. It does this by observing the current rate of change of the error.
Step 4: Know that by predicting future errors, the derivative controller helps the system respond more quickly and smoothly.
Step 5: Understand that this prediction helps improve the stability of the system, making it less likely to overshoot or oscillate.
