The PID Algorithm 8. The value of Functional Operation Diagrams is lost if the basic operation is obscured by excessive detail. Basically I’m trying to get PID values of a spinning DC motor and I’m using IR sensor to get the rpm of the DC motor… whenever I put my finger on the DC motor, the rpm values will change thus allowing to get outputs of PID values to control the DC motor. of feedback control system design that captures the essential issues, can be applied to a wide range of practical problems, and is as simple as possible. You want to control a temperature process that is driven by a semiconductor relay using SIMATIC S7 PID Control and want the PID controller parameters to be set online using the PID Self–Tuner. Considered as one of the best and common use controller in industrial control systems, PID controller can provide control action design for specific process requirement by tuning the three parameters. Guidelines related to the different components of the fuzzy controller will be intro-duced shortly. qxd 06:08:2004 6:43 PM Page 19. Process Identification and PID Control enables students and researchers to understand the basic concepts of feedback control, process identification, autotuning as well as design and implement feedback controllers, especially, PID controllers. CLASSICAL CONTROL DESIGN METHODS 19. In this section we introduce their structures and indicate their main properties. Anytime you adjust how you do something based on previous results, you are forming your own control loop.
