Reference tracking using fuzzy controller (to lower FPS).
logic controller was able to reduce the frame rate after adjusting the load of the ren-
dering process. This adjustment took place over approximately 9,000 frames with an
observable error of about 3 FPS.
In Figure 6.11, the frame rate increases from 370 FPS to a target of 400 FPS.
Again, the fuzzy logic controller can reduce the load and track the new reference
