The automatic controller under this study is bult of the following apparatus:<BR>Process- Intersecting gill box.<BR>Detecting Means- High-frequency small capacitance measuring equipment. (Uster evenness tester)<BR>Final control element- Electric-oil pressure power actor. Positive, infinitely variable speed chain gear box.<BR>Control means- PID controller<BR>The major causes for variations in the static properties of the detecting means are:<BR>(1) Make-up of the measuring condenser.<BR>(2) Amplification degree of the measuring equipment.<BR>(3) Dielectric constant of the fibers in a measured sliver.<BR>(4) Moisture content of the fibers in the sliver measured.<BR>(5) Deviation of the adjusted point.<BR>The adjusted point is a point where the two frequencies of the oscillators in the adapter coincide when nothing is contained in the measuring condenser. This point shifts by variations in the temperature and relative humidity of the room.<BR>The time constant of the detecting means is about 0.20 sec in normal and 1.6 sec in inert.
