Abstract
This paper proposes a new coupled pitch and velocity control of a doubly-fed linear motor, which is applied for a novel mechatronic railway system based on the operation of shuttles. Compared with conventional trains, a single axle under-carriage is developed for the shuttle. The primary of the linear motor is installed between the rails and the secondary is fixed on the axle only via the middle. In order to prevent the secondary from pitching and maintain a constant air gap between the primary and the secondary, the secondary windings are divided into two parts to be supplied separately. A decoupled pitch and velocity control is introduced in reference one in detail. Because the currents for pitch control don't contribute to velocity control. They cause higher power losses of the system. Therefore, a coupled pitch and velocity control is developed and presented in this paper.
