This paper is concerned with the theoretical behaviour of the linear synchronous motor as a propulsion means for a high speed vehicle. The performance during acceleration and steady state operation is obtained from a set of state variable equations which are solved using a digital computer. The inherent performance is oscillatory with little damping. A general fedback control scheme is presented which provides damping and control of the force angle (the angle between the vehicle fields and track field). Velocity and force angle errors control voltage magnitude and frequency of the power conditioner (cycloconverter). The effectiveness of the control scheme is measured in terms of its ability to have the vehicle follow a velocity profile, to maintain a constant force angle and to eliminate fast changes in the cycloconverter output voltage.
