Laboratory Exercise 4 Ball in Tube – PID Control Introduction There are three parts to this lab divided into three weeks. Week 1 will discuss instrument linearity as well as manual and auto control of the process. Week 2 will discuss auto-tuning and the process of controlling the ball for various step increments in auto as well as control in manual. Week 3 introduces various tuning concepts and their results. The following screens are the screens for operator use with this PID block.

They may be accessed during the lab from the HMI screen. When powered up, the ball rises to the top of the tube and then back down to the rest position. These screens show the status of the ball at various times. The purpose of the process is to suspend the ball at various heights. The figure above is the ball-in-tube experiment.

At right is the display. In the middle is the PLC, then the tube with laser at top and fan at bottom. The power supply pictured at left is not used. The primary screen for the Lab is: The three function keys are labeled with the following: F1 - Output Control – screen control to pick the screen above F2 – Graphs – screen control to pick the graph screen – next page F3 – PID Param – screen control to pick second screen – next page The PID PWM button toggles between the manual and automatic mode of the PID controller. When in manual, the button says Manual PWM and the student can enter the percent output of fan to control the air speed.

Air speed is controlled in this mode by entering a number in percent in the blue tab Output PWM on the next screen. Manual To change the height in manual, set the button above to Manual PWM and on the second screen, set the blue tab to a percent from 0 to 100. This sets the output to a percent on of the 24 V power supply to the fan. The figure below shows various percent on times for the fan. Auto To change the height of the ball in auto mode, click the button to PID PWM.

In this mode, the PID algorithm is automatically adjusting the PWM of the fan to achieve a height of the ball set by the percent height on the next screen’s green tab Setpoint (PID) . To change the auto set-point, click Setpoint (PID) . In auto mode, the value set is a percent of the height of the tube. For instance 10 or 10% would cause the fan to control the ball to 10% of the total height of the tube (if everything is properly calibrated). The actual height of the ball can be read from the Laser Input at the left of this screen or directly from the yard-stick attached to the tube.

Use the following screen to change tuning parameters for the block: Procedure – Week 1 There are two different relationships in this portion of the lab. One involves the laser and the ball’s position. The other involves the PWM output of the fan and the height of the ball in the tube. In each case, the input or (x) variable can be manipulated and the output or (y) variable observed. This lab involves determining the linearity for each of the relationships.

The procedure involves going from the low value to high value in small increments and from high to low in small increments. If the output value saturates (goes to 100%), all remaining input values may be skipped. 1. Collect values of output (y) for laser input vs values of input (x) of ball height (from yardstick). To do this, set the mode to PWM (auto) and adjust output % from 0 to 100 in increments of 10.

Then repeat from 100 to 0 in increments of 10. 2. Collect values of output (y), ball height vs values of input (x) or PWM %. PWM % represents a number for the percent of time the pulse to the motor is on. To do this, set the mode to manual and adjust the output % in 1% intervals starting at 10%.

There will be a point at which the ball takes off. This threshold will then allow the ball to reach the top without further adjustment. Then move from high values to low values. You will see a relationship that is different when the ball is at the top and the percent is lowered. 3.

Graph of Laser Output vs Ball Position: You may want to use the graph at the end of the lab report or generate the graph automatically using XLS (in scatter x-y mode). 4. Graph of Ball Height vs PWM%: You may want to use the graph at the end of the lab report or generate the graph automatically using XLS (in scatter x-y mode). Questions: 1. Are these two relationships linear?

2. Is linearity necessary to have an automatic operation? 3. Procedure – Week 1 cont. 5.

Use the system in auto ( PID PWM ) to control the height of the ball. Set the set-point to a height and observe the ball’s movement. Move the Setpoint (PID) from a low value such as 20% to a higher value such as 60%. Describe movement of the ball as it moves to 60% height. 6.

Now switch to manual ( Manual PWM ) and try to control the height to the same height as in the auto mode. Describe the movement of the ball in this mode. Is it harder to control to a set height? 7. Switch the system back to auto and hold your hand over the tube so as to cause a restriction (but letting some air through).

What happens when controlling the ball to a set height? If you hold your hands on the vents for a much longer time, what results are observed? Do not hold your hand near the fan at the bottom of the tube!!! 8. Do the same procedure of holding your hands on the vents with the system in manual.

What happens to the ball’s position when controlling the ball to a set height? 9. Now vary the set-point from a high percent to a lower percent while in auto mode. This is the reverse of the step function above. Move the set-point from 60% to 20% and observe and record the graph for the negative step function.

10. Vary the set-point by a great amount while in auto. Set the set-point at 10% and then enter a step to 90%. Record the results. Are these results different than those previously recorded?

If they are greatly different, reduce the step to a lesser percent to determine at what point the results seem to be more like the step function from 20 6o 60%. 11. Reverse the process and set the step to 10% from 90%. This is the reverse step. Record the results.

Appendix 1 – Portions of the Program in the PLC Open the project ‘PID’ from the zipped PID file. Then from the Portal View, go to lower left corner and click ‘Project View’. From this view, follow your instructor’s instructions for compiling and downloading your project to the PLC and HMI attached to your station: You will see in the project tree a main (OB1) and Cyclic interrupt (OB30) program. In OB30 is the PID block. From this block you can observe the PID block and its response.

Click on the figure in the upper right corner of the PID block and the box at the bottom of the page will appear. The status of the controller may be controlled from this screen or from the HMI. Either will give the same results: The procedure for download and going online will be given by the instructor.

Paper for above instructions

Part I: Food Diary

For this nutritional analysis, I maintained a daily food log for seven consecutive days, recording everything that I consumed, including snacks and drinks. The following is a summary of my dietary intake for Day 1:
- Breakfast:
- 1 cup of Cheerios (about 28g) with ½ cup of 2% milk (about 120ml)
- Morning Snack:
- 1 medium apple
- Lunch:
- 2 cups of mixed salad greens with 2 tablespoons of balsamic vinaigrette
- 3 oz grilled chicken breast
- 1 whole wheat pita
- Afternoon Snack:
- 1 small yogurt (150g)
- Dinner:
- 1 serving of spaghetti (about 1.5 cups cooked) with ½ cup marinara sauce
- ½ cup steamed broccoli
- Evening Snack:
- 2 cups of air-popped popcorn
Over the course of the week, this process continued with varied meal choices but following similar portion measurements.

Part II: Nutritional Analysis

Nutrient Intake Report from the Food Tracker

After logging my food for Day 1 in the SuperTracker, I generated a Nutrient Intake Report.
1. Nutrient Deficiency Assessment
According to the report, my intake of dietary fiber was below the recommended daily intake of 25 grams for women (U.S. Department of Agriculture, 2022). I consumed only about 15 grams, primarily from fruits and vegetables. To improve fiber intake, I plan to include more legumes (e.g., lentils and beans), whole grains (such as oats and brown rice), and high-fiber fruits like pears and raspberries (Slavin, 2005).
2. Nutrient Excess Assessment
The report indicated that my sodium intake exceeded the recommended level of 2300 mg per day, coming in at approximately 2800 mg. The primary sources were processed foods such as marinara sauce and the packaged salad dressing (CDC, 2023). To mitigate this excess, I intend to make homemade dressings, choose low-sodium canned goods, and reduce the consumption of processed snacks (Jacob, 2021).
3. Dietary Changes for Improvement
To establish a more balanced diet, I aim to make the following changes:
- Increase fiber-rich foods, such as incorporating beans into my salads.
- Reduce sodium by preparing more meals from scratch instead of relying on packaged goods.
- Substitute snacks like chips with healthier options such as nuts or vegetable sticks (Epicurious, 2021).
