A nontraditional course in electromechanical systems for engineering technologists

Texas A&M University teaches a required course in electromechanical systems to sophomore and junior mechanical and electrical engineering technology majors. The course transitions students from calculus and physics perquisites to more advanced courses in design, applied vibrations, automation, and industrial/real-time controls. Students study analysis and modeling of dynamic mechanical, electrical and mixed systems using classical methods and simulation. This class must introduce students to advanced engineering topics at levels ideally matched to student abilities to assimilate the material. The intent of this paper is to discuss several innovative laboratory and instructional approaches used to introduce topical materials to such a mixed student audience. Topics are initially taught using a systems or component assembly approach emphasizing the need to identify and model the individual components of larger systems. Students then directly assemble component models into one or more differential equations based on governing physical laws. These equations are numerically simulated and system response characteristics investigated. After some experience in evaluation of various dynamic systems is accomplished classical time and frequency solutions of linear 1st and 2nd order linear differential equations are presented and tied back to the earlier course material. The common mathematical solution processes integrated in the course are intended to act as a unifying force in developing an understanding of cross-disciplinary engineering problems.
