This question involves the use of an Excel spreadsheet [PIO tuning] provided with the assignment on Blackboard.

The spreadsheet' forms a PID Loop Simulator. From the screenshot below (Figure 21 it can be seen that spreadsheet simulates a process with a first order response that is modelled by entering values for its gain, time constant and delay (represented by the parameters IC, T and L respectively).

The PID controller is set by entering values for its gain, integral and derivative settings (parameters C, I and 0).

Provision is made for setting the Simulator to open-loop by entering a '0' in cell all of the spreadsheet. A '1' entered in the cell gives the closed loop response.

Question
a) Figure 3 shows the open-loop response of a process modelled by the parameters 1( = 0.75, T= 50 s and L = 20s.

Determine suitable PID controller settings for the process using the 'open-loop response' method.

Include in your answer a copy [screenshot1 of the spreadsheet showing the response with you PID settings.

b) Use the simulation to find the correct PIO settings of the controller by another tuning method.

Include in your answer a copy [screenshot1 of the spreadsheet showing the response with you PIO settings.

c) Compare the two methods of tuning used in (a) and (b) above in terms of ease of use, practicality and end result.
