PID tuning through SCADA in SCADA systems - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to set the proportional gain (Kp) in the PID controller.

SCADA systems

pid_controller.set_kp([1])

Drag options to blanks, or click blank then click option'

B1.2

C2.0

D0.5

💡 Hint

Common Mistakes

Using a very high Kp causes system instability.

Using zero Kp means no proportional control.

The proportional gain (Kp) controls how strongly the controller reacts to the current error. Setting it to 1.2 is a common starting point for tuning.

medium

Complete the code to set the integral time (Ti) in seconds for the PID controller.

SCADA systems

pid_controller.set_ti([1])

Drag options to blanks, or click blank then click option'

A1000

C100

D10

💡 Hint

Common Mistakes

Setting Ti to zero disables integral action.

Setting Ti too large slows correction.

The integral time (Ti) helps eliminate steady-state error by integrating the error over time. A value of 10 seconds is a reasonable starting point.

hard

Fix the error in the code to set the derivative time (Td) correctly.

SCADA systems

pid_controller.set_td([1])

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Using negative Td causes runtime errors.

Using non-numeric values causes syntax errors.

The derivative time (Td) must be a positive number to predict future error trends. Negative or non-numeric values cause errors.

4fill in blank

hard

Fill both blanks to create a dictionary with PID parameters for tuning.

SCADA systems

pid_params = {'Kp': [1], 'Ti': [2]

Drag options to blanks, or click blank then click option'

A1.5

B10

C20

D0.1

💡 Hint

Common Mistakes

Mixing up Kp and Ti values.

Using zero or negative values.

Setting Kp to 1.5 and Ti to 10 seconds provides balanced proportional and integral control for tuning.

5fill in blank

hard

Fill all three blanks to create a PID tuning dictionary with keys and values.

SCADA systems

pid_tuning = {'Kp': [1], 'Ti': [2], 'Td': [3]

Drag options to blanks, or click blank then click option'

A2.0

B15

C1.5

D0.5

💡 Hint

Common Mistakes

Swapping Ti and Td values.

Using zero or negative numbers.

This dictionary sets Kp to 1.5, Ti to 15 seconds, and Td to 0.5 seconds, a common PID tuning setup.
