Control system theory of operation

Technical Report ·
OSTI ID:6906867
Control of the field of heliostats is accomplished by means of a distributed computer control system consisting of a minicomputer located in the plant control room and a network of data buses and microcomputer-based controllers located at the heliostats. The reflective surface on each heliostat is rotated about azimuth and elevation axes by means of a gear-drive unit and electric motors. The actual azimuth and elevation angles are determined by means of incremental optical encoders and a microcomputer, and the microcomputer provides the logic to turn the drive motors on and off as required.
