This paper describes the performance of a superconducting linear synchronous motor control system used for a transportation vehicle by using an exact dq0-axis mathematical model. The paper first shows the detailed block diagram of the speed control system, which includes the blocks of propulsion force and speed EMF computations. A detailed discussion is devoted to the design of the control system. A cascade control system with PI controllers is designed as a numerical demonstration. It is also pointed out that the cascade control structure is a natural form for the power feeding method with three inverters. Performance simulations are shown for severe track conditions such as tunnel and track gradients as well as in a normal case. It is demonstrated that integrator windup of the speed controller can occur in the case of a severe condition in which one of the inverters is disabled. The authors present a design with more robustly stable performance by designing an antiwindup controller.
