Abstract
A system is described for controlling the movement of a vehicle over a guideway having a specified length. A signal is generated which represents a commanded absolute position of the vehicle on the guideway. A vehicle position transducer provides a signal having a value representing the actual position of the vehicle on the guideway which is compared with the commanded position to provide a position error signal. The speed of the vehicle is controlled in accord with the value of the position error signal. The commanded vehicle position signal is varied with time in a manner to provide desired vehicle motion characteristics including vehicle jerk and acceleration and deceleration values. The system also provides for a constant velocity control mode.
