Lecture 8 - Proportional-Integral-Derivative Control

For Lecture 8 we'll complete our discussion of PID controllers by adding the derivative term. The main points of this lecture for derivative action include:

  • Derivative action is typically on the PV not the Error
  • Derivative action helps to dampen oscillations by slowing down a controller action that is moving the PV too quickly to Setpoint (SP).
  • Derivative action can create undesirable response with significant measurement noise
