ET410 Assignment

Developing a Work Breakdown Structure

1. Watch videos 9 thru 13B of the Microsoft Project Tutorial.

Read the tutorial and get the link to download Microsoft Project HERE immediately if you did not start the process last week.

• • Using Microsoft Project software develop a WBS for your project

  • Include tasks for such things as equipment specifications for vendors, vendor bidding packages, evaluation of bids and vendor selection

• Include a title page and any references you used.

• Update your Lessons Learned Document.

Note:  Break down your tasks to the lowest level possible. The more detailed your WBS is, the more accurate your scheduling and budget will be!

ET495 Assignment

The Root Locus Method

1. Watch video “EE495 – Week 4 – Lecture”
2. Read Chapter 7 in the text Modern Control Systems, 12th Edition.
3. Work the following problems:         
   1. A unity feedback system has the loop transfer function: L(s) = Gc(s)G(s) = K / ((s(s + 3)(s2+ 4s + 7.84)           
      • Find the breakaway point on the real axis and the gain for this point.
      • Find the gain to provide two complex roots nearest the jω-axis with a damping ratio of 0.707.
      • Are the two roots found in (b) dominant?
      • Determine the settling time (with a 2% criterion) of the system when the gain of part (b) is used.
   2. The loop transfer function of a single-loop negative feedback system is: L(s) = Gc(s)G(s) = K(s + 2.5)(s + 3.2) / (s2(s + 1)(s + 10)(s + 30))           
      • This system is called conditionally stable because it is stable only for a range of the gain K such that k1 < K < k2.  Using the Routh-Hurwitz criteria and the root locus method, determine the range of the gain for which the system is stable.
4. Save work in a file with the title: “HW4_StudentID”, with your student id substituted in the file name.  Show all work for full credit.
5. Upload file “HW4_StudentID”

ET495 Lab
