For every engineer engaged in the design of the linear controllerthere will be many more involved in the design of logical controllers for the manufacturing equip-ment.One of the main problems for teaching linear controls is the lack of good design implementations.In electrical and computer based systems, linear controllers are relatively easy to develop. But inmechanical systems these become much more difficult to implement. For example, consider thatsimple aerodynamic drag leads to non-linearities. Examples of components and implementationsfor different disciplines are shown in Table 1.Consider the

One can then "prune” the tree and select the“best” possible design structure. This method can also be applied to other fields of engineering.1. IntroductionIn recent years, teaching engineering design is getting more attention in engineering education. Thisis due to the ABET Engineering Criteria 2000 initiatives, which have changed the way instructorsdelivered their courses. In electrical engineering, ABET requires that all electrical engineering coursesintegrate design throughout the curriculum, and now there is also a need to demonstrate outcomeassessment, and to check whether a program achieved

We spend many hours doing fundamentaland basic tasks, many of which are repetitious; the students take data, alone or perhaps with apartner, record it and then forget about it. It is not until they enter the job market that they applytheir knowledge to real world applications.Based on experiences such as just described, it has been said, that colleges do a lousy job ofpreparing engineers for the real world.

Role playingactivities may be divided into four stages1,6: 1- Preparation and explanation of the activity by the teacher. 2- The classroom preparation of the activity 3- The enacting of the activity (the role playing) by the class. 4- The discussion of the enactment known as debriefing.This type of hands-on instruction is supported by the educational research in learning theory andcognitive development.

There are various programming proceduresavailable, which make use of advanced technology: 1) programmable scientificcalculators and equation solvers, 2) spreadsheets, 3) mathematics software, 4)applications software, and 5) programming languages [1].

IntroductionA design project is usually a capstone course in traditional engineering education. To completea design project, students are assumed to have completed all required courses and have mastereda comprehensive knowledge in discipline so that they can apply what they have learned to thedesign project. A new approach is to teach fundamentals of engineering design (FED) tofreshman students. The first objective of this approach is to allow students to learn theengineering subject matter right from the beginning 5.

First used in the 1950’s, it has since been known by termssuch as Continuous Quality Improvement and Continuous Process Improvement as well as beingclosely tied, and almost synonymous, with the umbrella expression called Total QualityManagement (TQM).In an article in Quality Digest, Danny Langdon [1] states: Continuous Process Improvement is designed to utilize the resources of the organization to achieve a quality-driven
