The vast majority of controllers found in manufacturing plants use a combination of Proportional, Integral and Derivative (PID) control. These controllers are easily understood, and there are only three controller values to set up when attempting to achieve an acceptable system response. This paper looks at one industrial application of a PI controller, controlling the speed of a casting drum in a polyester manufacturing plant. The desired objective of the controller is to minimize the variance of the casting drum speed when in steady state. It therefore makes sense to compare a Generalized Minimum Variance Controller with the present PI to see if any improvements can be achieved.
