Abstract
The present invention provides a high response inexpensive microprocessor based digital control system. The digital control system uses only one detector that detects only one motion characteristic of the device controlled by the system. In the preferred embodiment, the digital control system controls the field orientation, the position and the velocity of a movable member of a brushless motor by creating commands that represent the desired position of the movable member 1024 times per second. The system also provides methods for improving the accuracy and precision of the system.
