Course Objective and Overview:

In this laboratory, we investigate fundamental concepts of control systems and apply them to improve the performance of dynamical systems. We also introduce computer software to help design and analyze control systems.

 

Prerequisite/Corequisite:

EEL4657, "Linear Control Systems"; some computer programming experience is assumed. 

 

Textbooks:

Laboratory manuals will be distributed by email.

 

Please Note: Every lab will start with a 15 minute quiz to verify readiness for the lab experiment.

 

 

 

Labs start on Monday, 1/26.

 

Schedule:

 

 

Week of 1/26: Frequency Response Experiment

Week of 2/2: Bump Test Experiment

Week of 2/9: Model Validation Experiment (summary report about the three experiments in this group is due next week).

 

Week of 2/16: Step Response Using PV Controller

Week of 2/23: Ramp Response Using PV Controller

Week of 3/9: Ramp Response with No Steady-State Error (summary report about the three experiments in this group is due next week).

 

Week of 3/16: Step Response with PI Control

Week of 3/23: Step Response with LEAD Control (summary report about the two experiments in this group is due next week).

 

Week of 3/30: Cascade Control with Ideal PD Controller

Week of 4/6: Cascade Control with Practical PD Controller and Servo Dynamics (summary report about the two experiments in this group is due next week).

 

Grade:

Grade is determined by the pre-lab assignments, the quizzes, and the lab reports. Each quiz carries a weight of 5 points, while each individual lab report carries a weight of 10 points. There are 4 pre-lab assignments with a weight of 10 points each; and 4 summary reports with a weight of 15 points each. The maximal number of points for the course is therefore 250 points.

 

Course Policies:

Safety First! Although the voltages you will be dealing with are unlikely to hurt you directly, care should always be taken when dealing with electricity. When soldering, you should wear safety glasses and protect your hands. Be careful and ask questions if you have any doubts.  Use common sense. In an emergency, know what to do.

Keep your area clean and uncluttered. Report any broken or damaged equipment to your TA.

 

Organization

Each lab group will consist of two members, if at all possible. However, each student submits an individual lab report each week. Many labs depend on the previous week's lab, so students must retain copies of all previous lab reports for reference.

 

Students must prepare each lab and complete all pre-lab assignments before coming to the lab. Assistance with pre-lab assignments can be obtained from the TAs by attending their office hours or contacting them by email. Pre-lab assignments are due at the beginning of the lab period.

 

 

Missing a lab

Students must notify their TA in advance, if they must miss a lab. Missed labs must be completed before writing the lab report (partner's data cannot be used). Make-up labs will be scheduled individually.

 

 

Lab Reports

A report is due after every lab. In addition, after certain sequences of labs, a summary report is also required, as indicated in the lab schedule. Weekly reports should follow the format listed below; summary reports should follow the format suggested in the lab manuals.

 

Reports must be typed (except equations and special characters) in the following format:

 

//TypeEEL4657L, the Lab #, your TA and your name here

 

Objective:

//Describe the purpose of the lab in one or two sentences

 

Data:

//This section is for all the data you got during the lab. Do not restate the procedure. Assume the reader is familiar with the lab manual. Present your data in a compact, clear table or list. Be sure to use the correct units. Describe and justify any deviations from the stated procedure.

//You do not need to include all calculations in the body of the report. If a result was calculated, state so and refer to an attached calculation page at the end of the report. The calculation page may be handwritten.

//You may include your plots here or attach them to the back of the report. Be sure to label all figures and include axes scales and units on all plots.

 

 

Discussion:

//Explain your results here. For example, answer questions such as "Did the controller achieve the desired specifications?". Be sure to answer all questions posed in all the sections of each lab assignment.

 

 

Conclusions:

//Summarize your results here. Often, you will be asked to compare the performance of one controller to another. This comparison should be included in the Conclusions section.

  

Academic Honesty:

All students admitted to the University of Florida have signed a statement of academic honesty, certifying that they will be honest in all academic work. Please uphold your obligation.
