Online quality control of multivariable systems. S. Ramaganesan et al. Hydrocarbon Processing, September 1994, 73 (9), 51--58.
A two-part procedure is described for unifying engineering and statistical process control in order to achieve total control of single-loop systems. The first part involves selection of a suitable control law. Block diagrams for multivariable and decoupled control systems are described and illustrated and the operation is discussed in mathematical terms. The second part involves analysis of closed loop control data to make these amenable to statistical process monitoring. Various closed loop responses are illustrated, and total quality control of single-input single-output systems is extended to multivariable systems. A simulation example is described. 8 refs.
