Control of Linear Synchronous Motors involves a number of low level issues of motor control—such as sensing precise position, controlling current in stator windings, and obeying commands from high level controllers—and high level vehicle control—such as stopping and starting, switching and merging, limiting speed and acceleration, synchronizing relative motion, preventing collisions and accidents, and dealing with failures. In most cases there is a master controller that directs vehicles based on simple commands but in other cases it is desirable to allow an external agent to provide more detailed control—such as synchronizing motion between a vehicle and a robot or allowing human operator control. This patent describes a versatile control scheme that allows both simplified high level control and, when or where necessary, control by an external agent. The result is a transport system and method that provides efficient and precise movement of vehicles on a guideway.
