... STRUCTURE OF A DIGITAL CONTROL SYSTEM To control a physical system or process using a digital controller, the controller must receive measurements from the system, process them, and then send control ... effective implementation of a PID controller. Finally, we consider nonuni- form sampling, where the sampling frequency is changed during control opera- tion, and multirate sa...
