Introduction to Instrumentation and Control Systems Using a Pendulum Mounted Air RocketCourses on engineering instrumentation and measurement typically have two objectives,introducing the students to essential and modern engineering instrumentation and developing theability of students to plan, execute, and analyze engineering experiments. The project describedin this paper encompasses all of these objectives and introduces students to practical aspects ofcontrol systems. The multi-week laboratory exercise requires the students to interface withlaboratory hardware and modern instrumentation with only limited guidance from the instructor.The self-guided problem solving approach to instrumentation gives students a deeperunderstanding of the nuances and complexity of developing and implementing multi-componentinstrumentation systems. Additionally, the students are required to develop a limited controlsystem that fires the rocket in response to position or acceleration feedback in order to achievethe highest swing height. Since this class precedes the formal controls systems course in ourcurriculum, conceptual control system theory is provided in a one-on-one basis in the lab. Inessence the laboratory serves as a ‘just-in-time’ controls course and sets up the formalmathematical controls course that follows. This paper includes the detailed design of the airrocket thrust laboratory apparatus and computerized data acquisition setup. Schematics andspecifications of the instruments are included along with a typical student data and analysis.Finally, student surveys were conducted and analyzed to assess the both general and specificoutcomes of the laboratory experience.
