Practical Implementation Issues with a PID Controller

PID controllers are some of the most common and effective controllers in use today. Despite their relative simplicity, there are several issues that you should be aware of if you plan on using a PID controller. In this video we discuss some of these issues such as derivative noise and integrator wind-up. We also present several solutions to these problems and discuss their integration into a larger control architecture.
