A magnetically levitated train is operating in Berlin, Germany. The M-Bahn 1600-m line represents the current state of worldwide systems. Fully automated trains can run at short intervals and operate with excellent energy efficiency. The control system for the levitation of the car is shown in Figure P10.34. Select a compensator so that the phase margin of the system is 45° ≤ P.M. ≤ 55°. Predict the response of the system to a step command, and determine the actual step response for comparison.
