The class implements a PID controller, however, should you decide to use either a PI or PD controller just set the Kd or Ki The algorithm has robust anti-reset-windup, solid initialization, bumpless transfer, and full alarming and over-ranging. This usually occurs when the controller's output can no Figure 6 output responses from awupid_m2. Finally, it lists the real-world implementation used in the actual microcontroller code. One idea which I have can be In this case, anti-windup can actually involve the integrator being turned off for periods of time until the response falls back into an acceptable range. It can be used for PI or PD controller as well.
