Systemanalyse und Reglerentwurf am Beispiel einer elektromagnetischen Aufhängung
A 74-page German Studienarbeit (student research thesis) from the Institut für Mess- und Regelungstechnik, Universität Karlsruhe, submitted in 1980 under Prof. Dr.-Ing. F. Mesch. The work performs a system analysis and PID controller design for an electromagnetic (magnetic) suspension — an inherently unstable, nonlinear plant — and demonstrates how the linearized closed-loop system is simulated on an analog computer. Topics include derivation and linearization of the equations of motion, measurement of the force-distance characteristic and optical sensor curve, root-locus controller synthesis, cascade current-loop design, normalization for the analog computer, and a revised laboratory experiment guide ('Analogrechner II').
