Commercial process simulation software makes it easy for experts to develop very complex models with thousands of equations. But how well re these models used? Remember the admonition of Box [Box, G. E. P. (1979). Robustness in scientific model building. In R. L. Launer & G. N. ilkinson (Eds.), Robustness in statistics (pp. 201–236). New York: Academic… (More)

A question that often process control engineers face is for what class of processes one should use model predictive control that requires solving numerically a constrained optimization problem repeatedly on-line. The alternative is to use analytical control, such as P, PI, PID and differential geometric control, which do not require the on-line… (More)
