A Technology Approach to Magnetic Levitation Steven Barker and Ron MatusiakBuffalo State College
Presentation Outline • Introduction to Buffalo & EET Program at BSC • Why Maglev AGAIN? • Maglev Summary in Pictures • Critical Components • Maglev Tuning - ET Approach • Control Systems II Course -Centered around the Maglev project • Other Diagrams of Possible Interest
Introduction to Buffalo, Local Industry, Education, Engineering Technology • Buffalo Population: city ~0.3M, region ~1M • Industry: automotive, chemical, food, aerospace, computer support, numerious small manufacturing • Education: 4 CCs, 15 colleges, 4 universities, 2 commercial colleges • Buffalo State College: Engineering Technology, Diversity, Control Systems • Outstanding Lab Technician
Why Maglev AGAIN? • Demonstration for control system courses • Desire to share inexpensive design with others • Project-centered Controls II course for EET • Demonstration for college open house • Demonstration for high school recruitment
Maglev Summary In Pictures • Hardware-Overview Picture • Close-Up Picture (Ball, IR LED & Detector) • Control-Circuit Picture • Control-Circuit Diagram • Component-List Table
Critical Components • Electromagnet • Derivative gain • Short leads • 10k Hz sensor signal isolation • Diode across the electromagnet
Maglev Tuning - ET Approach • Sanity Check: voltage_D & air gap & current_I • Derivative gain (K_D): turn off • Proportional gain (K_P): Increase Until ... • K_D: Increase slowly (May also have to simultaneously trim K_P.) • Air gap: about 1/2 cm • Electromagnet current: about 300 ma. Did not overheat. • Ambient light still has some effect.
Control Systems II Centered Around The Maglev Project • Lectures on classical frequency responses - Bode Plots (3 weeks) • Students build, test, and tune the maglev system (4 weeks) • Students build MATLAB Simulink model of the maglev system (4 weeks) • Lectures on frequency response stability (3 weeks) • Review and traditional final exam on frequency responses (1 week).
Other Diagrams Of Possible Interest • A Student's Simulink Model • Measuring Magnetic Force vs I and Z • Frequency Response of the Derivative Block • Measuring the Air Gap • Digital Control • Various Electromagnets • Possible Laboratory Experiments
