Study of P.I.D. Controller Trainer, Model: CPID – 101.


Today in the fast track of development. Proportional–Integral–Derivative (PID) Control action is the most widely used in industrial process like sugar, paper, chemical, food and any other manufacturing industries. These manufacturing process systems are usually slow, complex and are characterized by relatively incomplete or uncertain mathematical description. Therefore, PID Controller is used in such situations, because of  the  parameters  the  PID Controller may be adjusted experimentally.

The complete unit is housed inside a metallic cabinet having the simulated building blocks like error detector, delay, integrator, time constants, amplifier, etc. on the front panel. All the necessary switches. potentiometers and test points are  provided on the front panel. Fig. 1 show the diagrams of the system.
