Adjusting The Digital PID

Frequency response of the digital PID compensator is

determined by the Kp, Ki, Kd factors. These factors are

stored in nonvolatile memory and are loaded in the controller

at power on reset. The system designer sets the PID

compensators frequency response using user interface

software. The designer enters the frequencies of the

desired poles and zeros and user interface software

calculates the Kp, Ki and Kd factors. the software will

calculate and display the frequency response of the

feedback and the closed loop system.

FZ1 = Frequency of first zero

FZ2 = Frequency of second zero

FP0 = Gain * frequency of first pole (A DC*F P0)

FP1 = Frequency of second pole

RP2 = External Resistor used for third pole

CP2 = External Capacitor used for third pole

FP2 = 1 / (2 * π* RP2 * CP2 )

The software will calculate the frequency response of the

PID controller and the closed loop system as in figures 20

and 21 below.
