Control Using Wireless Transmitters

Exercise

This workshop provides several exercises that can be used to further explore the control using a wireless measurements.

Step 1: Open the module that will be used in this workshop and observe the control and simulated processes.

Step 2: Initialize the Performance Index (IAE) and then change the SP parameter of both control loops by 10%. Observe the control response using a plot of the setpoint, control measurements and output.

Step 3: Note the IAE and the number of communications for the wireless and wired control. A significant difference should be seen in the number of communications for wired vs wireless control that were required to respond to the setpoint change.

Step 4: Initialize the Performance Index and change the Disturbance input from zero to 10. Observe the response of the PID and PIDPlus to this unmeasured process disturbance.

Step 5: Note the IAE and the number of communications for the wireless and wired control. A significant difference should be observed in the number of communications for wired vs wireless control that were required to respond to the unmeasured process disturbance.
