Lab Time: Tuesday, 10:30 a.m. - 1:20 p.m., Sci. & Tech. I, Room 2B
Graduate Teaching Assistant: Tugba Erpek
         Office Hours: Wednesday, 1:30 - 3:30 p.m., and Thursday, 2:00 - 4:00 p.m., Sci. & Tech. I, Room 2B
Prerequisites: ECE 421 or POI. 
       ECE 422 is not a co-requisite for this lab.



The faculty supervisor for this course is Dr. Beale, Room 257, Science and Technology II, 993-1596.  The GTA will be responsible for providing assistance to the students during the lab and during his/her office hours.  The GTA will also be responsible for all grading in the lab, and will set standards for the grading.  The weighting of the various experiments will be based on the number of weeks assigned to the experiments.

Reference material for this lab course includes your ECE 421 textbook or any other text dealing with automatic feedback control at the undergraduate level. A list of references is provided at the end of this syllabus. Students are also encouraged to look at the design examples and design procedures found on the ECE 421 web site.

The objective of this laboratory is to enable the students to strengthen their understanding of the design and analysis of control systems through practical exercises.  This will be accomplished by using modern software resources to analyze and simulate the performance of realistic system models and to design control systems to satisfy various performance specifications.

The control systems laboratory consists of four separate units.  Each unit consists of one or more experiments. Unit A is a review of basic compensator design techniques.   Unit B involves compensator design for a system involving time-domain specifications,  uncertainty, and nonlinearities.  Unit C involves the design of a control system using frequency-domain specifications, and the evaluation of various configurations of the compensator.  Unit D involves compensator design for a system using frequency-domain specifications for a non-minimum-phase system.

Students in the lab will be divided into groups of 2-3 students each.  Students will document each experiment with a description of their procedures, results of their analysis or design, and plots as appropriate.  The reports for the various experiments within a particular set will be turned in to the GTA at one time when the set is completed.

Although students will work in teams to carry out the experiments, each student is required to submit his/her own lab report. Lab reports MUST be done individually. It is an honor code violation to submit another person's work as your own OR to allow your work to be submitted as another person's work. Any reasonable suspicion of an honor violation will be reported.


Unit B -- 4 weeks:
The transfer function which is to be used in this set of experiments represents the relationship between the heading angle of a ship and the angle of the rudder used for controlling heading.  A compensator will be designed for the nominal linear system model, and the performance of the closed-loop system will be evaluated.  Following that, nonlinearities and changes to the ship model will be introduced, and their effects on performance and stability will be investigated. Simulation of the system will be done in SIMULINK.
Unit B.1, Unit B.2

Unit C -- 2 weeks:
This set of experiments involves the design and evaluation of a compensator for controlling the vertical velocity (depth rate) of an underwater vehicle having zero forward speed. Specifications are given in the frequency domain. Comparisons in the time-domain and frequency-domain will be done for the compensator in its normal series configuration and in the Proportional+Derivative with Derivative on Output Only (PD-DOO) configuration.
