This paper deals with a guidance performance of a Maglev vehicle, which is guided originally by the interactions between the onboard superconducting magnets and the induced currents of short-circuited coils on the ground. Although the original electrodynamic guidance system may have a sufficient spring modulus, the damping factor is not enough so that it may not provide a good ride comfort for passengers. We notice that the armature coil currents for propulsion can generate normal forces, which can be used for guidance. Based on our methodology of dq analysis for the linear synchronous motor (LSM), we show two ways of guidance regulator design by using the property of second order system, and a pole assignment method. The results show that the d-axis currents of LSM armature coils are generated appropriately, establishing a high performance of vehicle guidance dynamics.
