Consider the data shown in Table 12E.1. The target value for this process is 200. (a) Set
Question:
(a) Set up an integral controller for this process. Assume that the gain for the adjustment variable is g = 1.2 and assume that ï¬ = 0.2 in the EWMA forecasting procedure will provide adequate one-step-ahead predictions.
(b) How much reduction in variability around the target does the integral controller achieve?
(c) Rework parts (a) and (b) assuming that ï¬ = 0.4. What change does this make in the variability around the target in comparison to that achieved with ï¬ = 0.2?
