Abstract
A process control system is disclosed in which process variables are treated as mapped in n-dimensional space, where n is the number of orthogonal directions. Three functions, set, check, and term, provide the link between expected and actual conditions. The check and term functions operate on orthogonal coordinates. Each parameter has a guard band to provide a soft boundary for the parameter.
