Anti-windup for PID control | Understanding PID Control, Part 2

The first video in this series described a PID controller, and it showed how each of the three branches help control your system. That seemed simple enough and appeared to work. However, in practice, an ideal PID controller introduces several problems that you need to protect against when dealing with imperfect systems. This includes saturation, which is a common nonlinear problem found in real-life situations. This video expands beyond a simple integral and discusses anti-windup methods to prevent integral wind-up in PID control. ------------------------------------------------------------------------------------------------------------------------------------- © 2018 The MathWorks, Inc.
